....anyone use any (besides those mentioned elsewhere)? no need to answer...just filling a page. but I don't (except perhaps caffeine--but that's a side effect of chocolate- -& Tylenol or whatever for occasional aches) I couldn't change anyone's mind if I tried.....but if you don't, do you think you ever would in the future? if you do, what would persuade you to stop? would you try to influence someone else's decision? I'm forever digging, trying to understand...but my shovel is dull.....
