Anxiety
"I was prescribed this drug for anxiety I took it home and managed to take it for 2 days but immediately noticed severe insomnia that after two days made me stop taking it. On top of the inability to sleep despite feeling tired I had absolutely zero appetite. In the little over 48 hours I had only managed to eat a handful of cherries... 
However when I was on the drug I did notice less irritability and increased fatigue which I attributed to not sleeping or eating."
