@alanism- I was given Xanax along with Klonopin 20+ yrs. ago for panic attacks & anxiety. The Dr. said to only use the Xanax in a pinch if a panic attack came on strong because it works real fast whereas the klonopin builds up in your system and works long term, but often not quickly (especially when I was newly taking it). Anyway I had taken once as I was driving on a freeway (not on my favorites list) and had a panic attack and decided to pull over and sat on the side of the road for over an hr. waiting to get the courage to continue driving. It ended up making things worst for me and I never took it again! I have had several friends take it and it worked better for them, but was very, very additing and ended up they were saddled with a long taper to get off of it. I would encourage you to stay clear of that one for sure!
