I've messed with psychedelics such as shrooms and some pure LSD on occasion plus I smoke my bud, but nothing I'd ever taken can come close to being as destructive as alcohol. Never had any real personal problems with drinking, and very rarely drank that much, but I haven't touched alcohol in five years, and now I am healthier than I've ever been and in the best shape since I was in my early thirties. But like you, I wish I had the knowledge I have now, back when I was much younger.
