Hi, I'm worried about my dad. He was Type 2 for several years but has been injecting insulin for 6 months or so. He has drunk some alcohol since but has today drunk quite a lot and gone to bed without eating anything. As far as I know, he injected before eating at about 2:45, drunk from 3-7:30 without eating much (no injecting) and no injecting or eating since. I tried to tell him to at least eat some glucose tablets before going to bed but he has locked his door so I don't know whether he has or not. I know this isn't good but just how dangerous is this? Should I wake him immediately? In a few hours? Or should he be alright overnight?
