Like Mitch suggested, do a Wake Back To Bed. It is almost impossible to WILD when you first go to sleep at night. You could also try during an afternoon nap. You might have to figure out if you get a REM cycle in the afternoon, and when. Most people do.

You can adjust the timing of your WBTB to respond to how easily you fall asleep. If you fall asleep too quickly, stay up for longer. If you still fall asleep too quickly, try some green tea or B vitamins to keep you more alert.
