I'm taking it for depression. It helps me sleep (big dose at night) and a low dose during the day helps me keep calmer.

I didn't really mind the weekly blood tests - the hospital is a few minutes' walk from my school so I'd go during a free period. I'm now on monthly blood tests.
Also sometimes I'd have to have blood tests twice a week because my levels were off.

I actually lost weight since I started, I think because I tapered off olanzapine.

It helps my ptsd and it helps me sleep, regretfully I'm still as depressed as when I started (I started January 2016)
