Some of the SSRIs work well for some and not for others. I have been on many different ones (Paxil, Serzone, Prozac, Zoloft). Some worked for a few months, one didn't work at all, even after 6 weeks, and one made me panic more (I didn't think it was possible at the time) and puke my guts out. After years of trying just about everything, I am now happily on Leapro and have been on it for 2 years (the longest anything worked for me before was 10 months). If I need an extra boost to calm me down, I take Ativan. Oh, most important for ME to help with the panic attacks was to STAY AWAY FROM CAFFEINE (tho I do indulge in dark chocolate).
