I've learned to set 3 priorities for the day. Everything else gets left undone. Self care is my top priority.

I agree with most everyone who has already posted. I listen to my body and when it needs a day off I give it one. I also try to balance doing a project and resting. I take some time for myself each day, no matter how busy I am. I get enough sleep and exercise works for me too. It lifts my mood and helps me keep my energy up. Some days, nothing works, that is just the way heart disease is, so I have learned to do what I can when I have energy and rest when I don't, and balance that as much as possible.

Fatigue can also be caused by certain medications used to treat heart disease. The class of drugs known as beta-blockers are infamous for sleep disturbances and interruptions. Some people complain of very vivid dreams while on them. Depression can also lead to fatigue. Anyone that suffers from heart disease has to experience so sort of depression at one time or another. Speak with your cardiologist. I was switched from one beta blocker to another and sleep much better now.

You do not try to manage fatigue. You have to allow it to manage you. Listen to your body. Not the people around you, not things on your schedule, not any goals you have set for yourself. When your body says you are out of energy you need to rest and recharge your internal body battery.

I find that my sleeping patterns vary. Some nights I sleep soundly throughout. Others, I sleep for a couple of hours, off and on.
