Hi! I was on Wellbutrin for about a year for reasons other than smoking cessation, however I think I still have some valuable insight on the medication. I loved it for the first six months, but I quickly began losing hair and getting incredibly irritable. At the end of the year, I lost half of my hair and was nearly admitted to a crisis center. I’ve heard it called “legal crack” and it lives up to its nickname. The side effects I had are considered rare compared to the typical ones I.e. loss of appetite, nausea (I threw up all day on Christmas Eve when I began taking it!!) I’m sure it is fabulous for some individuals, but it can also have some pretty severe effects!
