ya know, i had a long time problem with those. a few years back i was hooked up with an RN, she would steal scrip pads and dea #'s and call in scrips to drive thru pharmacies. we, most of our friends, were all hooked on them hard. those and ultrams. both of those have big time negative sides. especially if you are into the lifting scene. those drugs interfere with muscle contractions and some other bullshit. sorry for being vague and cryptic, but that shit didn't help my brain cells either.
