I know you're a lightweight when it comes to any man made chemical but the Xanax works because your body has a system do deal with it. We produce the chemicals Xanax provides naturally everyday. The job of anxiety relief can come from many natural sources, exercise, meditation, etc. but the pill works quickly and is in no way going to fuck you up. Next day hangovers from a small dose of Xanax are unheard of.
You're dreaming if you think it harms your normal system.
