Olanzapine as anti-emetic before SN - how much (time)?

[Mich517]

I'm going to ctb by Sodium Nitrite in capsules soon. I also have Olzapine. How much should I take this before and how much time towards ingesting SN?
I have 10mg tablets of Olanzapine and considering ingest 25g of SN.

 

[deck of cards]

I have the same question. I don't want to puke out the sn. Im on Ritalin, benzos ,Fluoxetine and Olanzapine .
Do I need to adjust the dose or do I take it like every day and drink sn?
