I never did find the book on Amazon by Dr. Jesse Stoff Epstein. I was doing okay with my diet and exercise program, and suddenly this month I have crashed for no discernible reason. I am barely able to drag myself around the house. I have noticed MANY MANY supplements mentioned on this site, and I'm just wondering which ones truly work, or is it just a matter of trial and error? I have lost weight because I'm trying so hard to follow a healthy diet, but now my mental state is about as low as it can go. I really need help to manage this illness. I thought I was getting better, but a year into this whole mess and I'm worse than I was at the beginning. Can anyone recommend supplements that have truly worked? Or medications? This is especially hard in a COVID world.
