I have suffered from panic attacks. I was on Paxil for a short time, but my doctor and I agreed that, in my particular case, medication was not the best option. She referred me to a program at a local hospital that used biofeedback therapy. Though the program seemed very good, I never did go through with it, for a variety of reasons.
Since that initial series of attacks, which happened about 10 ago, there are still times when I get panicky, but I've always been able to "talk myself down" using deep breathing and other relaxation techniques.
In the end, I think I really just needed to work through some personal issues that were causing/contributing to my attacks. Everyone is different, and I don't know the particulars of you and your situation. So this is not to say that you shouldn't take medication. But, like the previous poster, I do urge you to consider and investigate alternative therapies (biofeedback, meditation, etc.), particularly if you are not satisfied with the treatment you are currently receiving.
