Yes, I have. Not to the point of requiring an ambulance, but certainly to the point of falling asleep in nightclub toilets, getting thrown out at closing and promptly falling asleep again on the nearest reasonably flat surface. That's very much a rarity nowadays, but on especially good or bad occasions, I will still occasionally allow myself to indulge to the point of throwing up. I will at this point still maintain the presence of mind to a) find a toilet, and b) realise that this is the part where I need to go home and get some sleep. (I also have the presence of mind to realise that it's an extraordinarily bad idea to have pieces of nondescript cooked animal from the rather rank kebab shop on the way home, but by this point I'm afraid I lack the self control to walk past empty stomached)
