"my doctor will not prescribe xanax, klonopin, or ativan for anxiety, but he was comfortable giving me a script for librium (chlordiazepoxide) 25mg capsules 4x a day for my anxiety.  worked well at the beginning, but like all benzo&#039;s, the efficacy wore off after about a month of use.  was great while it worked and it was very inexpensive!  tapered off then went back on it a few months later and it worked like a charm again! on and off usage for close to 5 years now."
