Welcome to the site.
If you do not have any tolerance to them, it might be an added risk as it increases nausea and vomiting. Opioids are notorious for causing vomiting and make many people sick to their stomach, let alone on an empty stomach (fasting req for SN). So that would be a deeply personal evaluation and should be evaluated whether or not it is too risky for that individual person. But even for someone with regular use and tolerance, a regular to moderate dosing, not taking a ton.
If you are thinking it would make you 'pass out' then you likely do not have a tolerance to justify wanting to add it given the heightened vomit risks.
If someone did the benzos (which are a luxury item) in the protocol that would be far more sufficient and better overall for that purpose.
With whatever you decide, I hope you find everything you are looking for.
