I took a 3 hour nap from 3-6 pm yesterday trying to have a lucid. I then went to bed from 11-7 with a WBTB/in MILD the middle, and it was very hard for me to fall back asleep. Was this because I got nearly 12 hours of sleep that night? I felt like masturbating to help me fall asleep, but didn't want it to hurt my chances of having a lucid, since some people here say it might.
