depression
"I've been on this medicine for about  two years and my experience has been positive. I feel happier, more comfortable in my skin, less irritable, mentally sharper than I've ever been. It's been very effective!  The only downsides have been sex drive and some inconsistency in it's effects.  Sometimes I feel as though the potency of the medicine can vary month to month. 
Last year I tried to slowly come off of it over a two month period. Unfortunately, all the symptoms started coming back. It was a reminder of how hard life was before this medicine. I wish all of you the best."
