depression
"I have been taking this medicine for 2 weeks now and I feel much better.  I was extremely depressed and unmotivated.  I tried taking Lexapro and the sexual side effects were severe and the benefits were not worth the trade off so I stopped taking it.  My psychologist recommended Wellbutrin as an alternative and I am SO glad that I tried it.  I am more focused in school, exercising, and have an overall more positive attitude.  The only problem that I have experienced is that I have a very hard time falling asleep and staying asleep at night.  It is VERY annoying, but worth it to me. No sexual side effects and no weight gain."
