By filling out the fatigue diary you can start noticing patterns and get a better picture of how you experience fatigue, and what you could do to lessen the impact of fatigue on your life.
Capture as much information as you can. This will help you to identify what might be making your fatigue worse or better. You can then complete the diary again once you have made changes and compare the two to see if the changes have made a difference. Think about marginal gains – they might seem to be insignificant, but if you make two or three changes, the impact could be big. Try to give as much information as you can. This will help you identify what helps and if there is a pattern.
