With all the discussion about SN and vomiting, I am wondering, why are so few people using gelatin capsules? That would make the SN intake tasteless. Or is vomiting as likely nevertheless?
It sounds attractive, and may work.
However - there's always a bloody "however" isn't there ? - I have a worry that the capsules may not dissolve in a consistent manner, and thus be delivered into the body gradually rather than in a single overwhelming assault, possibly allowing the natural methaemoglobin reductase enzyme to do its job and stop the SN dose from overwhelming the body's natural defences.
Somewhere in the various literature on the subject is a recommendation to open up any capsules of the supplementary drugs (anti emetics/antacids etc) and just take the powder contents. Presumably that is to aid rapid absorption, so a similar logic may apply to the SN dose. The advice may be in the Suicide Wiki pages (there is just so much comment on this subject, it's hard to find what you want sometimes.)
However - haha - the vomiting response is not just a response to a bad taste, is it ? The body tries to eject what it recognises as a poison or pathogen from the stomach regardless of how bad or good it tastes. We enjoy booze, but vomit when we down too much of it.
I have considered cooling down the SN solution as a way of masking taste. The freezing point of the solution will be well under 0 Centigrade, so a domestic freezer will do the trick.
Another way of administering SN and avoiding vomiting might be by suppository (rectal administration) but there is no way I'm going to ram fifty gel capsule up my arse.
