Dude, friend, I'm so sorry to hear how drastically your life has changed with this illness. I too can relate as I ran all the time, worked out almost daily at the gym and hiked and lifted weights as well. That is all my past self, prior to ME/CFS onset vs. after - now I have longer/larger cycles of PEM and smaller more immediate PEM but I never feel good/normal - it's always there. I just sent the request to my MD for low dose abilify, I'll have to take chances with weight gain. My illness has caused weight and appetite loss so I'm not as concerned other than having to get larger sized clothes and feeling self concious about weight gain.
