How do you stay awake?!!!

My baby is a very slow eater and suffers from reflex which requires more time after hes done eating. So from start to finish it can take anywhere from 1 to 1.5 hours to feed him and that’s if hes cooperating with me. On a bad night i have been up anywhere from 2 to 3 hours trying to get him to go back to sleep. Well during these times I can hardly stay awake. I’m afraid I might fall asleep with baby in my arms.

How do you mamas stay awake during those late night feedings?
