I was on paxil for years, new Dr switched me to Zoloft because I was "taking too much xanax" . Been on Zoloft 25mg for 3 weeks now and have never had more anxiety and panic in my life!!! It is ridiculous!!! I got my old Dr back and she says to stop the Zoloft and go back to Paxil as of tonight. Do u think I will withdrawal from Zoloft 25mg after just 3 weeks on it???
