Lol..
Hmm, maybe since you just fall asleep, you should try FILD (Finger Induced Lucid Dreaming)
It involves moving your fingers the tiniest amount, so that you can just feel it.
This keeps your mind awake, but your body falls asleep, thus triggering SP.
Try looking up a User Tutorial on it in the Wiki.
I found that in the time that I used to try WILD, I also fell asleep to quickly, without achieving SP, then when I tried FILD, I got to SP twice I think.

Hope that helps.
