Wellbutrin SR
"I was taking this for depression for about 3 years and it was a miracle for me.  I stopped taking it when I lost my insurance for about a year.  The result was a weight gain of 20 lbs and severe depression (again)  I've been taking now about a year and the result is that I'm happy again.  I lost 30  lbs and experience an increased libido.  I've never taken any other anti-depressant besides Wellbutrin SR."
