Good old Valium.  Its got such a well known reputation so everyone knows what it is.  As someone who has taken it I was left very disappointed.  I was given 5mg 3 x day, nothing at all a happened.  In my opinion there are better alternatives my favourite being Xanax, while Klonopin is also a good one, Lexotan is crap.
Bottom line is is doesn't turn you into a zombie and it would only be slightly effective for SA/SP
