I sample tasted N and it was really bitter, I can't really imagine swallowing two bottles of this. I'm too young to buy alcohol so is there anything I can chase this with besides alcohol to mask the bitter taste? I feel like anti emetics might not be enough.
For the taste part, forget about the alcohol. I suggest drinking a traditional water based extract of kava, not only will it have the CNS depressant effects of alcohol, it also numbs your mouth due to its local anesthetic
properties.
About the antiemetic part, the odds are probably low, but if in doubt, buy some datura inoxia seeds and take ten (chew them well before swallowing). The scopolamine and hyoscyamine in them are anticholinergic muscarinic antagonists, meaning they'll directly prevent your stomach from contracting in a way that'll make you vomit. Also they act on chemoreceptors. I'm unsure how they'll react with the other antiemetics, so it's perhaps best to do one or the other unless it's stated otherwise.
