I have had CFIDS since December and have noticed marked improvement. I am able to be away at school, go to school full time and participate in a limited amount of outside activites. Of course accomodations have been made for everything, but I'm doing better than most I feel. I have problems with my appetite where I am just not hungry most of the time but I have been forcing myself to eat, especially today. Tomorrow is Yom Kippur and tonight I will be starting a 25 hour fast. You aren't supposed to ingest ANYTHING (even water or gum), but I'm still going to drink water. From your experience, is it safe to fast with CFIDS?
