Ok so I know I have asked this question before, I had been on Zoloft 200 mg for years, last fall it stopped working and have tried, prozac, Effexor, cymbalta, celexa and non worked like the zoloft did!! I am back on the zoloft 75 mg, I feel better then I did on the others but not great and is only been 2 weeks. DO I up the Zoloft or quit and try Lexapro? I am afraid that the ZOloft will not work for long and I will be back to square one and starting over.. Before I started the Zoloft again I had a bad reaction to Prozac with lots and lots of panic attacks etc!! Any comments would be great!!
