Upset with my husband for drinking

Is it normal for me to be upset at my husband for drinking? He doesn’t get angry or act any kind of weird when he drinks… he’s a sleepy drunk. So he will drink and then go to bed. We both work late at night, he gets off at midnight and I get off at 1am. Even though we work basically the same hours, I barely see him cause he’s always sleeping. I see him for a few hours in the morning before our shifts but I’m ALWAYS up at least 5 hours before him. He drinks basically everyday! Some days he won’t but I feel like most of the time he does. I tell him that I don’t like it cause I want to be able to spend time with him and he always says he won’t drink so much and then he literally just keeps drinking. I get it’s probably an alcohol problem now but I just don’t understand where it came from. We haven’t fought about anything other than recently me telling him I don’t want him to drink so much but it wasn’t really a fight, more like a conversation.

He says his work life is as normal so nothing changed there and we are fine so I really just don’t get where it came from.

I don’t know what else to do. He will say why is it such a big deal if he doesn’t act all crazy and makes me feel like I shouldn’t care so much.

What do I do?
