also, plain ol sugar,
yes, right out of the sugar bowl, in granular form,
can be applied, and absorbed buccally. I use that to treat hiccups all the time.
This really helps with those post-op hiccups that so many people get after surgery. Sure, if it's severe hiccups, there's drugs one can get ordered, too, but, plain ol sugar ---------under their tongue---------works great for post-op hiccups. Takes about 10 minutes.
Oddly enough, putting spoonful of sugar, also helps with people who have food lodged in their esophagus, too. (not stuck in their airway, of course, but, have swallowed something that is now kinda stuck in their throat, often, this is beef).
A spoonful or two of granular sugar sublingually (or sugar gel, or D50 IV) will help that esophagus open up, and wa-la! food drops down the rest of the way down their esophagus.
This also takes about 10 minutes.
sorry for derail.
