I have only been taking Budeprion for 4 days now, and the last 3 days have been excruciating! Horrible neck and shoulder pain that comes and goes. I wake up fine in the morning, but right around lunch time or a little after my upper back, shoulders and neck start to tighten and I get a terrible headache - usually only on one side of my head. I also have a fuzzy feeling in my head, and have a hard time focusing. The pain lasts until I go to bed, but then I wake up feeling relatively ok again in the morning. This is the first antidepressant that I have taken, and I know these kinds of drugs can take a couple of weeks before you start to notice anything, but I am really scared to keep taking the Budeprion because it makes me feel so awful. The worst part about the situation is that doctor actually prescribed me Wellbutrin, not this generic, and I just found out today that my insurance company covers both. I REALLY wish I would have done more research on this drug before I got the prescription filled. Now I have to wait a month before I can get it switched.
