Boyfriend going out and staying out late on bad nights?

My boyfriend and I have been dating for almost 2.5 years. I'm 21 and he's 23. We've always kind of butted heads about him going out and being out all night, but it's gotten a bit better recently. The problem I'm having is that he wants to go out tonight and won't say how long he is going to be out and how much he's going to drink. There are a couple problems here. 1) Our jobs never allow us to have a lot of time together. He spent the entire day doing his football draft/playing Xbox with a buddy online while I did the laundry and now he wants to go out tonight all night. 2) I have work in the morning, a 9 hour shift. We're currently down to one car. Since he has to work later he has to drop me off and then on my lunch come by so I can drop him off. He's fine with going out because he doesn't have to work in the morning. I do. And I'm one of those people that can't sleep until he gets home because I worry (not knowing when he'll be home...sometimes it could be 5 a.m.) 3) If he drinks whisky he comes home and gets mean verbally. 4) I'm a community service officer for the police here. I know the cops will be out and they don't have a DD (he refuses to drive though) and the last thing I need is to be woken up because something stupid happened. And anything he does reflects on me.

I know he needs time with the boys. I don't want us to be together 24/7, that's not the issue. I just get annoyed when it's this all night bad timing crap. I'd be perfectly fine with him going out and watching a game with his buddies but this all night bar special hopping stuff is aggravating. I had an internship 2 hours away this summer and he had all the time in the world to get it out of his system when I was gone. Argh. Any advice?
