Improve your sleep. Talk to your cancer care team about problems that may disturb your sleep, like depression, anxiety and stress.
Manage stress and emotions. You can help manage your fatigue by talking to someone about your feelings or doing activities to relieve stress and anxiety.
Pace yourself. Use your energy wisely to do the things that are most important to you.
Eat well. Eat healthy foods and lots of variety to have more energy. To stay hydrated, drink at least 6 glasses of water or other liquids every day (unless the doctor told you to drink more or less).
