"saying goodbye to wellbutrin. sadly i have to come off this medicine after 2 years.  it worked well for me, my weight went down and my sex drive went up.  however, insomnia got the best of me.  i could never get more than 4 hours of sleep a night and 6 with an ambien.  the lack of sleep is taking a toll on me sadly. i recommend this medicine and hope you don&#039;t have the sleep issues that i did."
