My husband tends to drink too much

Hey ladies ... Tonight my husband drank entirely too much while we were out with two other couples. Don't get me wrong we were all drinking but he doesn't know his limits especially in social settings it's almost like I'm his babysitter I have to pay attention to how much he drinks and his behavior like he was starting to nod off at the table and spilled beer all over himself. Ugh I'm so frustrated I shouldn't have to deal with this, we should be able to go out as adults and have a few drinks and he should know his limits to where he can still hang out and talk with our friends. He had to go to the bathroom to throw up and everything like seriously? How would you react to this? Am I over reacting? He's 27 he should know his limits by now!!
