depression
"I have been using Bupropion for 13 years and it worked better than any other antidepressant I have tried. However, as it happens it is not working nearly so effectively. The last 6 months and my doctor is having me also take Celexa to augment it. It does seem to cause a decrease in libido and sexual performance. I had no other noticeable side effects. But overall it worked well for me taking 100 mg twice daily for over a decade so I rate it highly."
