This is what I do:

i go to sleep at around 10:00 pm and set my clock for 2:30. When my alarm goes off at 2;30 i go do a WBTB for 10 mins. I lie there with my eyes closed on my side and try to go back to sleep while still being aware. I either fall asleep too quickly or i don't feel any vibrations or see any HI.

Note: The first time i tried to LD(WILD) i felt vibrations in my ear and got to excited.
