I have been on Zoloft for about 5 weeks and started feeling some pretty intense side effects (insomnia, anxiety, akathisia) for the past 4 days. I was on Prozac for the past 6 years and it eventually stopped working for me so my doctor switched me to Zoloft. I had been taking 80 mg Prozac and my doctor had me cross taper with 100 mg Zoloft for a couple weeks and eventually increased to 200 mg. This was all in accordance with my doctor's orders. I'm wondering if 200 mg is overkill? I think the only reason I'm on 200 mg, the max dose allowed by my doctor, is because I was on 80 mg Prozac which is the max dose allowed for that medication as well. Anybody else here on a high dose of 200 mg Zoloft?
