so then tell me if I'm crazy...i have found stackers to be the answer for everything - being able to study all nite, being able to party all nite....and most of all getting my buzz on quicker. granted, i WON"T take three at a time - usually only one or two a nite and if i drink - only one...but u start feeling good without having to drink a six pack and getting bloated and feeling like you're gonna puke... i've never had heart palpitations - but then again, i do it in moderation....
