Ah, for the days when a body could shake off a hangover in half an hour (not my first, though—that one, thirty-three years ago stands nonpareil yet). This trick, as you have discovered to your cost, is difficult to replicate much past twenty-five. Even less welcome than the physical symptoms, I find, is the sense of moral worthlessness (dear God, did I really say—and/or type, I suppose—that?) that is apt to accompany them.
This being said, however, it does sound as if you enjoyed yourself, and if your memory of the events is spotty you can always revisit this thread.
cordially,
