I've been on Zoloft for about 7-8 years now, with great results. last week though, I had a panic attack, which I haven't had in years, and now I've been dealing with the residual fallout. I asked my psych if I should increase the dosage of Zoloft after the attack. she said to increase it by 50mg, and I did for two days, and felt miserable.

Any reason why this might be?
