I have been on zoloft100mg for over a year and want to try and be tapered off. I also asked my Dr. to put me on wellbutin to help me quit smokeing. He took me from 100mg of zoloft to 50mg and added wellbutrin sr 150 too. Today was the first day and I felt horrible! Anxiety,just feeling crazy. Is this from the zoloft decreese? And was that too soon to go down that much? Or is this from the wellbutrin?
