Bupropion
"Suffer from SAD and PTSD tried Zoloft but had sexual side effects and still felt depressed.  I have taken Wellbutrin with much success.  Occasionally I have stopped taking it and the depression returns.  No sexual side effects and I'm back to my usual happy, positive and energetic self.  I've had to increase the dose to 300mg XL four times daily, still felt the blues and lack of concentration on 150 four times a day.  Doing great! No extreme side effects ringing in ears stopped, love the decrease in appetite and am now able to and desiring to exercise so the weight loss is a plus. Occasional nausea but able to deal with it.  I Love feeling back to my old self; highly recommend!"
