Yeah those meatball subs really hit the spot in post-pissup moments, when one goes searching for greasy food.
Something fatty and salty is what is needed IMO, I like those subs, only with about 4x extra lots of every cheese available and then I'll pester the person making it for more black olives until I can't wheedle a single slice more out of them, and the thing is bursting with olives. Other times, if its available then those charcoal pit grill place type big fuckoff double cheeseburgers, ideally with bacon and lots of it. If not, then the other favoured options are donner kebab and in a pinch, pizzza, peppperoni with a fuckton of olives over it and extra cheese.
For hangover remedies, I find a sedative-hypnotic like a benzo etc. helps a lot, either just enough to take the edge off, or else just to go and sleep it off, after drinking plenty of fluid. I prefer the seizure med I'm on. I'm used to it now so I have more leeway than anybody who doesn't take it regularly, but chlormethiazole is unique in that it also blocks alcohol dehydrogenase, preventing the conversion to the nasty ass, hangover causing acetaldehyde in the liver. It also means it potentiates the everloving shit on a stick out of alcohol, making even a small amount hit like a hammer.
So one MUST be careful with that combination, especially considering chlormethiazole is a powerful, barbiturate-like depressant. Does mean when I do drink, I don't need to drink nearly as much to get drunk, and that what is consumed, ends up having more of it pissed out as is rather than being converted to toxic intermediate metabikutes like acetaldehyde.
And AFTER the drinking, when the CNS depressant effects of alcohol have worn off and if I feel like shit, I'll go for a couple of buffered aspirin, a cup of 'andrews salts' similar to alka-seltzer, and an IM shot of morphine, or else insufflate the contents of a few IR oxycodone capsules, taking about 50mg or so.
I very rarely get hangovers. When drinking socially or simply to quench thirst I go for beers, lagers, ales etc. and those are not particularly suitable for one to become drunk on, not more than mildly so anyway. And my antiseizure med protects me at that level from any hangover.
If I want to get drunk, I'll measure out a quantity of pure ethanol then dilute it to a concentration safe for tissues, with something that tastes decent, like elderflower cordial concentrate, and drink it down in one shot. One is quite enough to get you to whatever stage of drunkenness one might wish for, in a few minutes, I find that the very pure, un-denatured lab ethanol gives less of hangover when not over-used. Presumably because it is far cleaner and more refined than drinking alcohol.
But the core hangover cure for me IF I ever get one, which is rare, I am not a heavy drinker at all. Is the andrews salts and a shot of morphine plus a sedative and a couple of buffered aspirin.
