Olanzapine as antiemetic for SN

[hellohello]

Hi, I have access to Olanzapine as an antiemetic. I have not taken it at all. I read that it needs to be taken regularly before ctb in order for it to work as an antiemetic for SN. My questions:

1. Can I take 10 days of Olanzapine and then ctb?
2. What is the regime for the day of ctb...do I need to up the dosage? Follow the 10mg x 3 times regime that Stan suggests?

Any and all information on this would help. Thanks!
