1. I like to sleep on my side to keep from having to swallow. Is this a problem when you normally sleep? There is no magic position for a successful WILD. Use whatever position is most comfortable or natural.
2. You can move around during your WILD, as long as it does not break your relaxation too much. Obviously, don't do jumping jacks half way through. For example, I normally start on my back, do some relaxation exercises, then roll onto my side to transition. Moving won't set you back too much. Feel free to stretch, scratch, or twitch. As long as it is helping you become more relaxed, you are making progress.
3. I think the most important thing during a WBTB is to keep the lights low. Incandescent bulbs, warm light, and no television. Just stay up long enough to be able to think straight.
4. If it takes me more than 15 or 20 minutes, my timing is wrong. It should take you about the same amount of time it takes to fall asleep on a normal night.
5. I like to imagine my body pushing into the bed. I alternate between my feet and my head. I just imagine them sinking. If my thoughts are racing, I will do some reverse blinking.
6. To keep motivated, I read through my favorite old dreams. You can do it during your WBTB so stay excited.
