If you're not used to taking it, it will flat out knock you on your butt.. Also, you might sleep walk and/or order expensive things online and not necessarily remember any of that in the morning. You'll also wonder how that foot tall high pile of candy bar wrappers go there and why your pants don't fit as well, anymore..
Xanax is awesome, tho.. So relaxing, provided you don't take too much to fall asleep with.. Normally they start you on .25mg and you'll work your way up to the white, 2mg bars, which are designed with one thing in mind: giving you the best sleep ever - at least until you get used to it, as it then loses its knockout punch.. Same with Ambien.. I've been on Ambien so long I don't even remember the last night I tried to sleep without it..
Friendship is like peeing your pants.. Everybody can see it, but only you can feel the warmth..
