This happened to me ths VERY first time i got drunk. I can thank my big brother for that one. Beer and wine did not mix well nor did the wine cooler LOL! BUT i was in the bathroom, puking in the toilet while shitting, i had class.
I remember when I got married. Apparently, my wife (now ex) didn't eat enough and they kept refilling her drinks and she got completely "shit faced".
When we left the wedding reception, she told me to pull over because she had to puke. When I did, she opened my truck door and began puking. A couple of minutes later, she fell out of the truck on into the grass. Fortunately though, she didn't fall into her own puke.
