Sertraline
"I'm a 25 year old male who has been on Zoloft for most of the past 4-5 years for anxiety. At times I took 50mg but mostly I took 100mg/day.

The drug's effects aren't as noticeable until you either stop and think about it or stop using it for a bit. I like to think of it as taking the emotional peaks and valleys in your life and compressing them. While that's a good thing for bad anxiety and what not, it also is a bummer that is works the same way with positive feelings.

Quitting the drug made me more irrationally irritable but not much else. My least favorite part of Zoloft is how it kills libido and makes it incredibly hard to climax. It's got it's upside but I am currently in process of trying something else"
