I somehow manage to stop myself drinking as soon as I get drunk so I've never had this problem, only thrown up once after a night out and thankfully it was right as I got home.
In front of a bar? Yes, I was sitting really near those elders and I was feeling so sick because I smoked something that was real, reeal **** and I started puking a lot, the funniest thing is that those guys just ignored me and just talked about football when I was throwing up everything
