Use magic to heal all the pains, and the hangover. Since there's still alcohol in him, decide that it's already been metabolised into sugar and CO2.
Get the helmet and review the latest A/V data.
Call the rest of the team to see if they're around or if they left already. "Hello, AGT47? Where are you guys?"
Not only are you exhausted, but you have multiple broken bones, a severe concussion and most likely brain damage. On top of having a horrid mix between a hangover and drunk.
Are you sure you want to metabolize alcohol into C02 and Sugar in this state? Are you sure doing that in the first place is the best of ideas?
Upon reaching Amadou, Regon performs a shoddy ritual to align his bones and stop any internal bleeding, using simple growth runes and very little chanting, only using a small amount of the local energy.
"Yer not wurf da spirit's gifts, next time, i'll be lettin' ya bleed ta deaf."
[11+0{Intentional minimal effort}] You stabilize Amadou and set the bones. He'll have a godawful headache in the morning though. It's probably advisable to have someone cart him over to the medical tent on a stretcher.
Regon took care of the basic healing, at the very least the bones are mended and there's no internal injuries. He's going to heal the remaining bruises and the hangover.
Is he exhausted? He's been asleep from whatever time he had the accident till now, and it's afternoon already.
As for drunkenness, he drunk enough for BAC 0.3 at 22:00, fourteen hours later he'd be below the driving limit in much of the world (0.08) and at 15:00 it'd be at 0.024, about a beer's worth. He needs the sugar better than the alcohol, and that amount isn't enough to cause hyperglycaemic shock either.
Drinking water would be a good idea, though, and he'll do so before converting the alcohol.
So, if you want to screw my character over again, it'll have to be about trying an experimental procedure, the rest doesn't apply.
