Can’t stay awake during night feedings 🥱

I’m having a really hard time staying awake during night feedings. I keep cold water by the rocking chair and make sure to have some, I’ve tried watching tv, playing on my phone, snacks.. nothing is working. I fall asleep every feeding and I’m terrified I’m going to wake up one of these times and baby won’t be breathing. Help!! What helps you stay awake during night feedings?

Edit to add: I feed him in a glider/rocking chair in our bedroom (where he sleeps) with a boppy on my lap and my feet up on the ottoman so we’re reclined and I always wake up still holding him and he’s safe. I’m just worried my boob will end up blocking his nose one of these times. He’s almost 4 weeks old.
