Mrs T, I'm sorry to hear you've had a fight. My fiancé is much the same, he works hard all week (nights) then has Fridays off and he just lets loose. I'm all for enjoying yourself and having a few beers with his mates but he writes himself off! I get cranky and just leave him wherever he is and come home to bed he usually comes knocking on the door at some ungodly hour and crawls into bed. I get pretty cranky at him when he acts like a d**k but he apologizes the next day and I can't stay mad... TBH I let it go pretty easily, I do worry that he will think it can continue after we have kids (one of the blokes he drinks with has 3 LO's at home and has a bit of a drinking problem) but I can assure you I won't be putting up with that! I would suggest that you pull him up on the drink driving and let him know that it's not on for not only his safety but everyone else's but this may just be the way he lets go of the stress of the week and unwinds?
