It’s painful and just awful. I was an RA in college and saw all kinds of stuff with alcohol poisoning, including convulsions and seizures. I really dreaded weekend duty because I always had a resident that did something stupid while partying. Things get very painful and horrifying when other substances are combined with the alcohol poisoning, including permanent injuries. So, OP, if you’re just curious and couldn’t decipher what you found on whatever medical web site, now you know. If you’re thinking about ways to die, call a hotline and get help.
