I was on Bupropin myself for quite a while, and it was quite effective in leveling out my moods and decreasing my depression. I felt a little too drugged for my liking at 300mg, so I was back on the 150 dosage until I stopped cold turkey just a few days ago due to some odd muscle issues (not related to the wellbutrin, though). My depression has actually come back quite acutely, so I'd say the medication is very effective.

The side effects from Wellbutrin are generally reported as very mild, though in rare cases they've increased people's negative psychological symptoms. Keep at it as long as you can, but if things get too squirrely, STOP and call yer doc., no matter how far away he is.

Luck&Love,
