As I said before the mentioned URL(
http://www.socialfear.com) has analyzed the various types of meds (Benzodiazepines, MAOI's, TCA's, SSRI's ,...) that are available in the SP case. Side effects are also mentioned. A quick glance in this article and similar ones reveals that klonopin is the most optimized (greatest effect while least side effects) for SP treatment. I think that Doctor's experience has also a great role in the case of mental diseases and it is recommended somewhere to ask your doctor if he or she has helped other people with SP.
But about myself. I deal with a very severe SP. My sleep was something similar to a calamity. I chose klonopin and prozac(flouxetine) by myself because I wasn't courageous enough to visit any doctor.
Now my sleep is normal. Of course I use klonopin at night and I haven't tested it at any other time. So I can't predict what would be happened if I quit it.
Also I can leave home easily now and manipulate my works which was a hardship for me before.
Physical symptoms are also reduced and I'm able to control my motions (head,eyes,trembling, … ) better than ever when I'm anxious.
At the end I think klonopin or similar meds can't cause any miracle. They only help to control our anxiety and it is a precious opportunity to change our taughts and improve our attitude with therapy or self-help methods.
Also this is a self-help guide which may be helpful:
