My P doc put me on Wellbutrin XR 150 about 5 weeks ago. Since then I've been embarrassingly clumsy. An hour ago I tripped and fell on my face in the drug store. The pharmacist ran over to help. It was so embarrassing. I've also been light headed when standing up, have bad brain fog, and sometimes I can't find my words. Does anyone else have these problems with Wellbutrin?
