I got drunk for the first time two days ago, the next day i had a horrible hangover, (threw up twice, had diarrhea multiple times and didn't eat anything because i couldn't hold anything down) today, i have some lower back pains, i keep hearing my stomach making noises and my urine was a very dark yellow color. Is this unusually bad? or will it go away? I also feel horrible in general, slightly depressed, definitely regretting the drinking and feel like I can't do anything.
