I have a few questions:

1. When I drink a lot of water before sleeping, I will wake up in my next REM cycle. Do I wake up at the very beginning or the end of the cycle?

2. What is the best time for DEILD? At the beginning or the end of an REM cycle (once I figured out when they happen)?

3. I have multiple cycles of REM in a night, should i set my DEILD alarm in the early or later ones?
