Thread: Can't find my REM time for DEILD/WBTB

But you can go by this:

We go through sleep cycles, each one is about 90-110 min long. At the beginning of the sleep, NREM is about 80 min long and REM is about 10 (for 90 min total). As you sleep, NREM gets shorter and REM longer, and after about 8 hrs of sleep NREM is 10 min or less and REM is the rest of the time.

Thanks for the guidelines on the sleep cycle. I do realize that it is best if I do WBTB after ~6 hours of sleep, since the REM cycles are longer around then. My problem is, if I wake up for WBTB after ~6 hours, I have a really hard time falling back asleep. Do you have any tips for this, or any idea why I can't go back to sleep? All I do is get up, go to the bathroom, and then try to go back to bed. I have no idea why it is so hard for me.
