Can antipsychotics be used as an antiemetic for SN?

[SHThrowAway213]

I'm supposed to be on Risperdone 3mg a day, don't take them but still have them around.
I also have some Amtriplyne 10mg a day and Omeprazole tablets 20mg tablets a day but don't take them either but are prescribed.
Would these be ok to take for the SN method?
I'm not sure what my regime would have to be.

High doses of Seroquel [an atypical antipsychotic] can be used. At least 300mg/day.

I have some olanzapine and I would be grateful if someone had some information on dosage because I found nothing in this forum so far.
