Ativan
"I was on Ativan for Generalized Anxiety Disorder with Panic Disorder.  It worked okay, however once I started seeing a specialist, I changed to Klonopin.  I find that Klonopin is much more consistent, meaning I don't feel it kick in and wear off like I did the Ativan, this apparently is due to its longer half-life.  I did find out the hard way, that these are abused by some people, so don't leave them accessible in any way.  I had mine stolen once, bad experience!"
