Hi,
First of all, I love to see someone else on here from the Chicago Area, so cool!
That sounds like quite a fast dose increase! My pdoc was always more careful and slow about that kind of thing. Though when my Primary care doctor was prescribing my zoloft for a little while and I was first started on it, she had me go from 25 to 50 within a few days. This was too much for me. I had dry mouth and an ongoing headake, and a couple days into the increase I woke up in the middle of the night extremely restless and anxious with my heart pounding ETC! It was very scary! I asked to be brought down to 25 mg and I was fine. My former Pdoc then took over, and increased it by half if she was gonna do anything. Now of course, I don't have a pdoc, and so have been on 50 mg since I moved from ma to here several months ago.
Anyway, I hope this helps. I'd suggest going back down and see what that does.
