"I am a 27 year old male, on this drug for 3 weeks so I can't really comment on it's efficacy, as it takes 2-4 weeks to start working. All I can say is it didn't help me. I took 40mg for 7 days, then went up to 80mg for 2 weeks. I had to stop taking it because of the side effects - I was getting severe irritability to the point where I was yelling at the top of my lungs at people for minor mistakes and generally grumpy. Based on this and other side effects - needing to urinate far more regularly than usual, heart palpitations, feeling down for no good reason and insomnia - my doctor decided it wasn't right for me.This is a rare reaction which is unlikely to happen to you, but if you get it, tell your doctor."
