Clozapine - how fast does it take away symptoms

I have been Clozapine for 6 days now. It has not taken away my voices yet, nor has it changed the nature of my voices. So my voices are exactly the same as they were off this drug.

As of today I am at 150mg/day (split into two doses). It goes up every 2 days, and I will be on 300mg/day by early next week.

Just curious if anyone out there has tried clozapine and recalls how fast it took to work especially in the context of hearing voices.
