Oh, I didn't mean drugs!! I meant controlling one's environment, having better support networks, etc. Though I do think it's perfectly acceptable to tweak neurotransmitters on a temporary basis with things like 5HTP or tryptophan or GABA or whatnot. But B vitamins for me are just as effective.
I've got lots more to write on this but will have to put it off until the weekend... Stay tuned!
