I have SN but it's hard for me to find a good source of anti-emetics. Do you guys think it's a really bad idea to do it without anti-emetics? I'm not really prone to vomiting. I haven't vomited for at least 5 years.
I think, per Stan's guide, it is not absolutely necessary. You can search on this site for threads on other's that have used this method. Some have vomited despite meto, some have appeared to have succeeded without. I guess you have to decide based on your own experiences with likelihood of vomiting.
edited to add: some have succeeded despite vomiting.
Possibly if you vomit immediately and have anything in your stomach that could negate or absorb the SN but many have vomited and succeeded. This is why I steer people to the actual anecdotes to learn for yourself
@Erase.myself vomited a lot and supposedly succeeded while @Lion84 took 2 sips, changed his mind but passed bcuz ems took too long. Each person is going to vary in some way.
In my personal opinion, I would strongly advise
against doing it without antiemetics if you possibly can. Even if vomiting doesn't cause the attempt to fail, it is still an unpleasant and non-peaceful experience to have during your attempt.
It's important to understand that the vomiting in response to ingesting SN (or indeed any kind of poison) is an instinctive survival mechanism, and is not usually comparable to any kind of vomiting you may have (or may not have) experienced before. So relating the SN scenario back to your own past experiences or likelihood of vomiting is unfortunately not very useful.
While some anecdotes do show people vomiting even with antiemetics, or not vomiting even without antiemetics, it's important to remember that overall vomiting is still
less likely if you take an antiemetic. See
this analogy for a relevant example. While individual experiences will always differ somewhat, there are nonetheless commonalities explained by physiology, one of which being that antiemetics tend to make vomiting less likely.
