depression
"This drug used to do wonders. I went on it because one antidepressant wasn't enough to get me out of bed and moving. It lifted me up and gave me the motivation to be able to take care of my daily living needs and hold a stable job.

The side effect that causes them to take me off of it was because it was making me manic (as I am bipolar) and it caused me to make quick, risky, and ill-advised life decisions.

Taking me off the drug has effectively stopped the quick life decision side effect, and after getting off of it, I've been able to think more clearly, be more mindful of my movement and thought-processes, and gave me a general feeling of wellness.

The negative of getting off of it, however, is that I lost my ability to sleep well."
