Susan Weaver--the fatigue that plagues your father is a familiar demon at our house. Peter has periods when he has to sleep--sometimes very soundly-- for 2+ hours during the day. If I read aloud to him, or we watch TV, he will fall asleep for sure! We had to give up the talking books, which were great when his eyes bothered him, because he fell asleep and couldn't get past Chapte r 1! :-( This seems *at times* to be related to where he is in the med cycle, but not always. I think it is common for PWPs. Various things have been suggested that seem to work for somePWPs (NADH, vitamin B, etc.) BUT nothing works for everyone, unfortunately. You might try checking the list archives on the subject. Good luck.... Camilla Flintermann,CG for Peter,78/7 Oxford,OH
