Help Standard SN Protocol + Opiods?

[broken_stoic]

I was looking at the standard pph SN protocol of:

• Anti-emetic
• Benzos
• Painkiller

Is there any harm in adding some opiods into the mix and if not, is there a recommended dosage and/or timing? I've never done any opioids before, so would have no tolerance. I can see there being some added risk of vomiting or such?

This is my question also. I have oxycodone, I have never used it so I have no tolerance. I think taking it before the SN would be most helpful since the chance of vomiting after the SN would waste the dose.
