HI. Today is my 5th day to take generic wellbutrin 150mg for depression. I havent had any problem - just noticed I have not been hungry. Today I was fine, ran an errand and while I was driving my throat felt strained/tightening - not like in not being able to breathe but just a tight feeling and I felt dizzy...I ran in to store and grabbed what I needed...then sat in car for a few minutes before getting back on road...my distance home was about a mile and half...i had to pull over one time because I felt this sensation I do not know how to describe - kind of dizzy/kind of panic attack feeling. Do these side effects go away? Is this typical? Have now that I think of it kind of felt like my jaws tighten at times like grinding....
