This topic was on Dateline the other night. I can't say shit about it b/c I'm hooked on stacker 3's...not even 2's...3's for cryin out loud..but this show scared me...I'm not a coffee drinker and I don't put anything else "herbal" into my body so I didn't think they'd do too much damage...who doesn't need a pick me up mid-day?....but coupled with other things you take, drink, eat throughout the day...it could prove very dangerous...just don't do what I did and mix stackers with red bull and vodka for an entire summer...you'll end up 100 lbs soak n wet and in the hospital....be careful people...
