I find it best to stop and rest when I get tired. Then I can usually do more. When cleaning the house, when I get to where the computer is in the middle of the house, I stop and read e-mail. After a little while sitting and reading e-mail, I can get up and vacuum some more. Also, I lay down every afternoon and take a nap for an hour. It is hard when you want to do things away from home. Last Sunday I was at a guitar festival all day. I took Provigil to stay awake, but I was still exhausted by the end of the day and ached all over. Part of the problem was that I didn't use my cane as much as I should have- that has always made my good leg sore.
