I was on Zoloft for 8 years for anxiety and got off for 10 months for the birth of my daughter. I then went back on for anxiety and did fabulous for 9 more years. I started to get a little more anxiety and decided to increase the dosage, but it only made me more agitated. So, I've since tried Lexapro to no avail and Prozac was way too stimulating causing agitation again. It's been 4.5 months since I've weaned off Zoloft (been on Lexapro for 5 months, Prozac for 7 weeks). Will Zoloft work again? Or, have I just built up a tolerance now and my body rejects it?
