I took Wellbutrin SR 150, and it made me shaky. When I upped to 300, I was a disaster. I was constantly dizzy and had a difficult time with depth perception. I also shook like a leaf and had little or no attention span.

I am and have been on 100 mg of Wellbutrin sr since the beginning of the year or so. It works with just a tiny bit of tremor. So I think it depends on the person. Zoloft was horrible for me. Paxil is fine. People react differently.
