What does an anti-psychotic do?

[SorenVC]

Hi. I've been diagnosed with undifferentiated schizophrenia, asperger, psychosis when I was 16 (also have ocd [You must be logged in to view images. Log in or Register.]) and been taking Olanzapine Zyprexa in different dosages. I think they started me with 25 mg then lowered it down. I am now 28 years old so I took it for 12 years.

When I was on 7.5 mg for the last two or so years I was getting days where I wake up with a headache and the headache stays and I go to bed with a headache. That's why I tried to get rid of it with no success. Everytime I told my therapist or my mom I have a headache they just said it doesn't come from olanzapine and my therapist said I should be on it for life.

Regardless of this my therapist lowered the dosage to 5 mg and I was feeling better for 3 weeks but today I received a headache full day again... I will ask her to reduce it to 2.5 mg and then I will take that for a month or so and then not take it anymore. 2.5 mg is the lowest dosage in pill form so what more can I do. I'm too lazy to ask for this olanzapine in liquid form or do a really slow taper...

So I have two questions:

1 what does Olanzapine or any anti-psychotic actually do?

2 does God want me to take olanzapine zyprexa and stay on this anti-psychotic all my life and just live with the pain? Or does he want me to try and break free from it like I will try now?

I always got rid of it cold turkey with no success but this time as I said I will get the 2.5 mg pills prescribed from my therapist and then one day stop taking them. I mean what more can I do at this point... Hope it works tho.
