I agree diet is most important. Supplements that helped me were L-glutamine and 5 htp. I take them every day without fail or I will turn into a blithering idiot. Not a pretty site. LOL . I also started taking calcium and magnesium and I believe that has helped as well. I take a really good probiotic as well as flax and fish oil. Maybe something like that could help you. I would try anything first to stay off the anti-depressants. I also have a set routine and certain routes I take to go to work. If I get off course it puts extra stress on me and throughs me for a loop. Remove as many stressors as you can. That has helped me alot.
