Or, start paying attention to micro awakenings we all have during night between dream cycles.
What I do, is I drink some water before bed. That wakes me up 2-4 hrs after that and if I'm not ready for WBTB then, I drink some more water to wake me up little later. Obviously, more water you drink, sooner it will wake you up.
I used to use this method for WBTB, now I use it to record my dreams.
