30 years of anxiety and depression. I finally discovered it was MSG. I love ramen, even the cheap stuff, and had been eating it since college. Other than that, I eat pretty well. Studies galore now about how preservatives and additives (flavor and color) can trigger people. Since I don't eat a lot of meat, I have a protein shake in the morning and I supplement with Arginine, Theanine and Lysine (essential amino acids). Be careful of some of the riskier supplements if you go down this rabbit hole. SAM-e is practically an SSRI and made me crazy (like SSRIs do). St Johns Wort sent me into a full blown blackout manic phase. 5-HTP gave me serotonin syndrome. I'd recommend cutting out crap and letting your body adjust before trying to add things back in.
