Boyfriend sleeps WAY TOO MUCH it's pissing me off :I

Okay! My boyfriend falls asleep at like 3 in the morning (as do I, but I still manage to wake up before noon and get my shit done.) anyways sometimes he even stays up all night playing video games! And it's annoying me because he wakes up at 5-7pm and he's missed two fricken job interviews because of his stupid sleeping schedule, and I keep telling him to fix it and he says he will but he isn't doing anything about it!!! Last time we planned to hang out at 1pm, and he didn't end up waking up until 3pm and had me messaging and calling him for two fricken hours and I'm so annoyed and done with him doing this. And I even make him set up alarms so he can get shit done instead of being a lazy sack of potatoes but that doesn't work either. What should I do about this??? It's on my last nerve.
