Falling asleep deer hunting has never been a problem for me, but I have done it a few times. Now duck hunting on the other hand is when i sleep the most. You get up at 1 or 2 in the morning maybe get 2 hours of sleep if any and by 9:30 i'm ready for a nap. Plus cattail beds in the marsh are very comfortable and after I get done making one I'm out like a light for 30 minutes or so. And if i hear wings,my dog whining or my buddy's shooting(those jerks) I know its time to get up.
