2 days overdue, husband keeps drinking

I’m 2 days overdue with my second and my husband keeps drinking. The past three nights he’s been borderline drunk. Tonight I poured out his bottle of wine (for the second time in three days) and he stormed off going to bed at 7:30 (leaving me, having contractions, to tend to our 2.5 year old). When the time comes I’m considering driving myself to the hospital and not allowing him in the delivery room if he has even a drop of alcohol in his system. Thoughts?
