Mary, I have gone nonstop since Aug 2007 and when I sat down to rest my eyes would close for about a half hour and then I would get back at keeping busy. 3 1/2 yeras later, if I am sitting about 3 PM, I still take a nap, not by choice, but from the treatments. Don't fight it like I tried to but take a nap when you need it. Good luck with everything. Yes, I exercise at least 2 times a day , doing 200 repitions per day . It seems to keep my mental attitude where it should be and makes my body feel better.
