I have been on Welbutrin XL for about a year now, and came off of it about a month ago. (on my own, no Doc) I cam off of it mostly becasue I dont have insurance and can not afford it. I thought I was ok, I was feeling fine. However, I am getting a little down again, and I can not just go to sleep. I have to play little mind games and stuff. Is there a more affordable medicine comparable to Welbutrin XL?
