I've only tried Xanax and Valium. I really can't understand what all the Xanax hype is about. Xanax just makes me sleepy, while Valium actually gives me a pleasant sort of high.
Either will do when coming down off something, though I very much prefer Valium.
I'm gonna be trying clonazepam (Rivotril) pretty soon so I'm curious what to expect.
