i hunt from dark to dark but always around 8:30 or so i'm ready to pass out...i guess it's cause i'm sooooooo relaxed and at peace that i just can't help it....if my eye lids get too heavy then i fall asleep for 20-30 minutes and then i'm good until about 2 ish....then it's time for another nap.try to bring high enery snacks, you can buy a bladder and fill it up with coffee...it'll stay warm., or you can start dippin'....have you ever fallen asleep with a dip in you lip while wearing a face mask? it'll only happen once....lmao...you'll be soooo traumatized that you won't do it again.....(that was a joke; don't start dippin')....day dreamin' works too...try getting a good nights sleep beforehand too...best of luck to you!!
