As someone who thought that this was a good idea, trust me, it definitely is not. I binge drink quite a lot during the weekends and sometimes during weekdays as well. SN and alcohol are both toxic compounds and regardless of how used to you are with one, the interaction between the two is going to induce severe nausea. Take this with a grain of salt because I "Believe" that I have a pretty strong stomach due to all the substances I've abused in the past, but even I wouldn't be confident in going through with this. Not to mention, that depending on what kind of alcohol you're consuming, it could be hoppy or sugary which could alleviate the nausea.
Overall, as someone who had planned on doing this exact thing for the longest time, alcohol and SN aren't a good match. If you want some kind of anxiolytic for your nerves, it's best if you don't rely on something like alcohol and instead look into Benzodiazepines/other forms of sedatives.
If you're absolutely deadset on taking SN with alcohol [I would seriously recommend against it], don't drink anything remotely hoppy or sugary [No beer, no Whisky]. Mixing SN with one of those would be your worst nightmare if you don't vomit immediately. It'll be like your worst hangover ever times a 1000. You'd essentially be dry-heaving trying to spill your guts until you can't and then some more. Take it from someone who's had experience with mixing various drugs with alcohol, but decided that SN is just not worth the risk.
Benzos are your best friend for quelling your nerves followed by other forms of sedatives which can put you to sleep before the more severe effects like tachycardia start to onset.
