One of my buddies b-day party is tonight, where I'm sure one drink will lead to another, to another five.....

I've been working out and on my bulking diet for five weeks now, and dont want to screw up my gains (which are coming along rather nicely), but I'm gonna give in tonight. I haven't drank anything since I started my bulk, and have followed my diet very well.

Should I bother eating anything tonight, and continue my meals? Or is that a bad idea when mixed with alcohol? I'm assuming it is a bad idea, and I should just drink a lot of water tomorrow?

Any comments?

Thanks!
