schizophrenia
"I've been taking Zyprexa for just over a year now and have seen dramatic improvements in my life. I used to be incredibly paranoid of people, was hearing voices and was delusional about my physical health. I'm on 20mgs of Zyprexa and most of my symptoms have cleared. Some of them remain, but they're much more tolerable than they used to be. 
The only drawbacks I have noticed are weight gain and slowed reactions but I'd rather live through those side effects than experience what I did before treatment."
