I have been working on having WILDs, too. I have also experinced the "pain" of my body trying to get me to move. I have found that I have the best luck if I go for about a mile walk before bed. Then I sleep for about 4 hours. I get up for only 5 minutes or so, but make sure I pee before I head back to bed. Then I focus on calming my body for a few minutes for, just repeat, "I am comfortable," or something like that. After that I just ignore whatever my body does to try to get me to move. That routine has helped me with the pain sentations.

Good luck!
