re: AbusedTampon, just because those ingredients didn't negatively affect you, don't assume that the OP would have the same experience as you. It's the Non-Event Feedback Loop, and it can be a very dangerous thing unless squelched in its tracks. You were probably just sharing your personal experience, but to me I got a sense of flippancy where if I was reading your post and I had just got a bottle and found out it had those ingredients you mentioned, I might decide a low dose wouldn't hurt. And yeah, it probably wouldn't hurt. Not right then, but the cumulative effects of ingesting those extra active substances are not worth it for the high, IMO, tho I sometimes take those mucinex pills as boosters. Long term guaifenisin abuse has been linked to kidney stones, among other things.
