He won't stop drinking before the baby comes....

So I posted a little while ago about asking my husband to stop drinking in case I go into labour as I would need a ride to the hospital and he is supposed to be my support system during labour. I asked him and he totally agreed.

Well he hasn't stuck with it. In fact he's off work for the next few weeks and all he does when our son goes to bed is drink, every night. If I were to go into labour right now I'd have to take a cab because he's not even remotely sober. Idk what to do! I keep reminding him that I'm not delivering my baby with him like that at hospital and he just says sorry then drinks. It's stressing me out😟 I'm due tomorrow.
