Yeah man, I'd just go to work. It's better to make money then to drink / smoke to excess and feel like crap the next day. It's even worse to suck it up and go to work. I remember one night I went to the bar till around midnight, then a party after until about 3:30 in the morning. I finally got home around 3:45A.M. before crashing until 6:30A.M. when I had work....that was a bad idea but thankfully I was working with another person who was equally hung over / still currently wasted as I was. I don't recommend it, and I won't do it again myself =P

There will be plenty of parties and always will be. Besides, it starts to get old after awhile.
