Clonazepam
"I have been taking klonopin for several years.  I find it helps more than the short-term benzos like Xanax and Valium.  For one with BPD, Bipolar, and Anxiety Attacks, this pill is a godsend.  I usually do not advocate pharmaceuticals, but I have never had my anxiety quelled like klonopin does.  It is highly effective for any type of anxiety, and stops panic in its tracks after 15-20 mins of administering. This is the only pill that i'm on that I advocate.  The only warning I have is that it has high potential for dependence, and the body gets used to having it constantly.  Sometimes it requires upping the dosage.  PLEASE start on 0.5 mg.  If your dr starts you on 1mg, it will bring on extreme fatigue, and decreased motor function."
