Why can't you get antiemetic from eBay? I could pm you the Bonanza link mine was from if you want. You can't do it with just those, you will throw up. You either need a dopamine blocker like meto, or DMSO to help it absorb. You can get DMSO at places like vitamin shops, health stores, and in some places pharmacies. But the problem with DMSO is conversely throw up if drink too much, not well-tested, and has the worst taste there is. I can't even imagine how bad DMSO with salt would taste. But you're going to horrible if don't take one or the other.
If you absolutely won't or can't use meto or DMSO, just but. When I was SN poisoned from putting DMSO+SN on my skin, nausea from the poisoning still even though I didn't swallow it. Cannabis helped the nausea, but it also wasn't severe. I'm still unsure if it's even worth testing as an antiemetic though since I looked it up and the stuff cannabis to help nausea is the opposite of a dopamine blocker. Its reason help me might have been something more related to dermatological SN poisoning that might not even apply to swallowing SN. But if I couldn't use meto or DMSO I'd use cannabis as an antiemetic because I'm stupid
