depression
"I've been on generic Wellbutrin xl 300 for 12 years . I was trying to quit smoking & this was recommended as it was also being marketed as Zyban at the time. For me, it helped with cravings and depression and I've never picked up another cigarette.  There are 2 things that bother me.  I cannot sleep without also taking Trazodone. I just drift in and out of a light sleep otherwise. The other thing that may or may not be related to WB is that I have chronic constipation.  I say may or may not because I'm scared to get off of WB to see if that's what's causing it.  Different drugs work differently on different people of course but, like another person suggested, it also kept me from gaining weight until menopause. Hope this helps."
