Too bad for Mr. C. Failed to grow up when others did.
I had similar experience with a friend. Years back while in school we went for a friend's party and it was fun then doing those things. I remember a had a mixture of six different alcoholic drinks and danced my head off. Days later, i was sick because of the mixture and it too me quite a while to recover.
Today whenever i drink out, i just do it responsibly.
