hell i had a friend that stayed with me for a long time and I saw that (now ex) friend loose WEEKS on end @ a time because of those things man.

But myself ive taken 12mg of xanex, and not felt ANYTHING unless i was drinking or smoking with them. So i just dont take them, it pointless for me. The meds the doctors prescribe you generally work lots better than what you can find on the street anyways.
