I don't tak Klonopin, only Xanax occasionally, but I did start Paxil (notCR) about six weeks ago for GAD and panic attacks and it's helped me alot I feel. I had racing
heart beats and lots of symptoms of anxiety and panic daily. Inderal helped the racing heart and slowed me down but the other symptoms continued, in fact escalated. I tried Buspar to no great effect but I would recommend trying the Paxil.. Some people have worse cardiac symtoms with SSRI drugs.
