So It's summer vacation for me, and I've become quite accustomed to falling asleep at around 2-3 am, and waking at around 12pm, or 8am if I have something to do / somewhere to be. Since I'm pretty damn tired at that point, could I treat it somewhat like a WBTB? I know that the REM cycles will not have started yet etc, but I feel the same (the tiredness) .. So what method of WILDING could I use?
