Yoga before bed?
I start on the floor -- a few walking planks, down dog, a couple of very slow sun salutations. And then I get on the bed and do legs up the wall over my pillow, hold a spinal twist in each direction for a minute or two, reclined butterfly pose, and then stretch out. I also have a strap so I can hold one leg up at a time in a hamstring stretch -- don't pull, just hook your foot in the strep and let the back of your leg relax. It is magical for my nighttime jumpiness.
