I took a Xanax once and fell asleep within 5 minutes before I even "felt" anything. A fellow food server had given it to me, and she swore that it helped her get through her shift. Thankfully, I took mine after my shift at home and woke up on that same couch 5 hours later, discombobulated (What happened? Where am I? What time is it?). I never took another.
Once, I took a (I can't remember the word, round? series? ) of steroids for 12 weeks in order to maximize my workout results. A fellow food server had sold them to me and I had to inject myself with a syringe in the ass everyday. It seemed to work but at the same time made me perpetually cranky. I never did that again.
There was that time, so long ago, where a skanky guy did a trick in the kitchen at the end of a party. He cooked up some cocaine in a spoon, gently playing with the lighter torch, until the cocaine melted, bubbled and smoked. Then we inhaled this smoke through a straw. I think this is called free basing. I immediately, and I mean immediately vomited. I never did that again.
I was prescribed Zyban once to quit smoking. After it caused terrible insomnia the first week, I turned into "mean" tornwordo. Nobody could wait until I got off those pills, including me.
I used to say that I would try anything once. I'm not so concerned about the legality of such things as I am with the likelyhood of getting caught. That's all that counts. In this way, I have discovered that most drugs are "bad" for me. That is, I don't see the benefit. But it is only from my experience that I speak, not because I have accepted what I've been told. Still, you probably won't be seeing me trying heroin any time soon.
