An ME/CFS activity diary, sometimes called a CFS activity diary, is a record of your daily activities, rest and symptoms. Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) causes severe, persistent fatigue that does not improve with rest, along with muscle and joint pain, headaches, difficulty concentrating and remembering, and unrefreshing sleep. Its defining feature is post-exertional malaise (PEM), a worsening of symptoms after physical or mental activity.
Keeping a diary can help you understand how ME affects your daily life and spot possible triggers. By recording sleep, activity, work and symptoms, you and your healthcare providers may be able to see patterns or changes that help inform treatment decisions.
What is ME/CFS?
Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a long-term illness that affects many body systems. ME and ME/CFS are names for the same condition. Its defining feature is post-exertional malaise (PEM): a worsening of symptoms after physical, mental, or emotional effort, often delayed by a day or more. Other symptoms include fatigue that is not relieved by rest, unrefreshing sleep, brain fog, and pain. In the UK, care follows NICE guideline NG206, which recommends energy management (pacing) and advises against graded exercise therapy.
What to record in an ME/CFS activity diary
Record only what is useful to you. Your ME/CFS diary might include:
- Daily activities: work, household tasks, social activities and any physical, mental or emotional effort.
- Sleep: how long you slept, how well, and any trouble falling or staying asleep.
- Symptoms: fatigue, muscle and joint pain, headaches, difficulty concentrating, unrefreshing sleep and any post-exertional malaise.
- Medications: what you take and the dose.
- Triggers: anything that may have triggered or worsened symptoms, such as certain foods, stress or your surroundings.
- Notes: anything else you noticed about your day and how you felt.
Chronic Fatigue Syndrome Activity Diary Example
A sample chronic fatigue syndrome activity diary entry can capture what you did, when you rested, and how you felt before and after an activity. For example, note a household task, a rest break, and any change in fatigue or other symptoms. Keep the wording factual and brief.
As you add entries, look for patterns that may help you plan a balanced day. A pattern is not proof that an activity caused a symptom. You can use CareClinic to record these details and review your notes with your healthcare provider.
What is a pacing diary?
A pacing diary is a tool used to track daily activities and energy levels in order to better manage symptoms of ME/CFS and/or fibromyalgia. Pacing is a self-management technique that involves balancing activity and rest so you stay within your energy limits and avoid triggering post-exertional malaise. It is the main approach recommended for ME/CFS in UK guidance (NICE NG206). By keeping a pacing diary, individuals with ME and fibromyalgia can identify patterns in their energy levels and learn to pace themselves in order to optimize their daily activities and manage symptoms.
Your pacing diary might include:
- Daily activities: work, social activities and other daily tasks.
- Energy levels: how much energy you had before, during and after each activity.
- Rest: the rest breaks you planned and took.
- Symptoms: fatigue, pain, headaches, difficulty concentrating and unrefreshing sleep, including symptoms that appear a day or more later.
- Triggers and notes: anything that may have worsened symptoms, and other observations about your day.
All of this can be stored in CareClinic. The Symptom Insights screen in Reports automatically shows which factors often come before changes in your symptoms, so all you need to do is record your day-to-day symptoms and health.
Why keep a symptom journal?
- Tracking symptoms: a diary helps you follow your symptoms over time and notice patterns or changes, including factors that make them worse.
- Talking with healthcare providers: a record of your activities and symptoms gives your providers more detailed and accurate information about how ME affects your daily life.
- Self-management: by learning how your condition affects you, you can adjust your daily routine to better manage your symptoms.
Using an ME/CFS activity diary in CareClinic
CareClinic combines a diary with a fatigue tracker and symptom tracking. Many people use it as a chronic fatigue diary. Used together, the diary and trackers help you see the connection between your symptoms and your daily activities, and identify patterns and triggers.
Log symptoms, activity and rest
You can log symptoms once or several times a day, and rate their severity and frequency as they happen. Try to be objective when you record them. Noting how you feel during a flare-up or a period of severe exhaustion is hard, but it can give you and your doctor useful information.
You can also log how long you sleep, any activity you do, and details about your diet. Tiredness levels for activities such as running errands or socializing can be tracked too, along with emotional symptoms such as stress and anxiety. Log as often or as rarely as your energy allows.
Spot triggers and patterns
Over time, you may see that certain activities come before your symptoms. For example, you might feel intense tiredness the day after a big shopping trip, or notice that flare-ups line up with your menstrual cycle.
If you record meals, you can check whether certain foods come before worse days. Mark the days you ate particular foods and see whether a bad day followed soon after. Do the same for good days, so you and your doctor can see which factors or activities they have in common. It can feel like a lot at first, but it gets easier with time.
See which symptoms affect you most
As you record your symptoms, you will see that some affect your everyday activities more than others, and that symptoms can interact to affect your quality of life. The fatigue tracker charts show how each symptom changes over weeks. You might find that pain was present less often than exhaustion. Knowing your most common symptoms, their intensity and their frequency helps you and your doctor focus on what matters most.
A pattern is not proof that one thing caused another, but it can help you plan a more balanced week.
Share it with your doctor
When you see your doctor, you will tend to talk about the symptoms bothering you on that day. A diary gives a fuller view. Detailed records kept by patients often help doctors understand a condition whose symptoms are not always clear, and they can help guide diagnosis and treatment.
If new symptoms appear, add them to CareClinic too. They may be related to another condition that overlaps with ME, and your doctor may need to adjust your treatment plan. You can also print your list of symptoms to refer to when you are offline.
Plan your days
As you become more aware of your patterns and possible triggers, it becomes easier to decide which lifestyle changes to make and to plan your schedule. A predictable routine can help, but it does not need to become your top priority.
Supplements & Vitamins and ME/CFS
Another benefit of CareClinic is that it can help you remember to take your medications, vitamins and supplements on time. Some people with ME/CFS ask about the supplements below. There is not enough evidence to recommend any supplement as a treatment for ME/CFS, and NICE NG206 advises that supplements should only be used to correct a confirmed deficiency or on medical advice. Talk to your GP before starting one. If you do take them, you can set reminders in CareClinic based on your own regimen.
1. CoQ10: CoQ10 is involved in energy production in cells. Small studies have looked at it in ME/CFS with mixed results.
2. Magnesium: Magnesium supports muscle and nerve function. It is mainly useful if your levels are low.
3. Vitamin B12: B12 is needed to make red blood cells. A deficiency can cause tiredness, so your GP may check your levels with a blood test.
4. Omega-3 Fatty Acids: Omega-3 fats are part of a healthy diet. There is not good evidence that they treat ME/CFS.
5. Iron: Iron deficiency can cause fatigue. Only take iron if a blood test shows you need it, because too much iron can be harmful.
Modafinil and ME/CFS
Some people ask about modafinil, a wakefulness medicine licensed in the UK for narcolepsy. The evidence for modafinil in ME/CFS is limited and mixed, it is not licensed for ME/CFS, and it is not a recommended treatment in UK guidance. It also has side effects and interactions, including making hormonal contraception less effective. Read more in our article on modafinil and ME/CFS, and talk to your GP or ME specialist before considering any medicine. If you take a medicine, you can log it in CareClinic with your symptoms so you and your doctor can see whether it helps.
Keeping a personal journal
Alongside your symptom diary, you may want to keep a personal journal about your life and the emotions you are experiencing. Writing about difficult moments can relieve stress and help you feel better about your condition.
A journal can be a trusted friend. You can record the moments worth remembering as well as the harder ones that come with living with a chronic condition. It might feel difficult at first, but it often gets easier.
Living with a chronic condition affects your quality of life, but you are not defined by ME. If you want, you can share your ME/CFS activity diary with family members and close friends. Opening up can be hard, but it can help them understand your situation better.
Tracking at your own pace
CareClinic helps you see the link between symptoms, activities and energy levels, and you can use it as often or as rarely as your energy allows. Tracking is optional. Over time, it can give you a clearer understanding of your energy and symptoms.
