bipolar disorde
"I suffer from Bipolar disorder and found that this drug works wonders. If I may say, this is the wonder drug they say that doesn't exist. Now, I would usually complain how I went from x stone to y stone, but I'm drastically slim, so it's done me well to gain 60 pounds. 

This medicine helps controls Psychotic disorders by allowing you that extra few seconds to respond, whereas before you would just react without thinking. It is known as a major sedative because, well, it slows you down. This drug is usually used in conjunction of Antidepressant medications, and mood stabilizers. 

I suggest this drug, don't listen to the annoyed people who are now 20 pounds heavier. There is nothing to complain about if it helps, then it's worth every pound"
