Hi, All. The following is based on my personal experience as an RLS sufferer for more than 50 years. Though my findings are preliminary, the results thus far are promising. If borne out by the experience of others, the suggested regimen may offer a prompt, no-cost, easy to apply, home remedy to bring night-long relief to others suffering from RLS. For those who prefer not to read the entire comment, I have described the regimen in a discrete paragraph at the end.
When I was experiencing the worst of DAWS, I gained temporary relief while laying on my loveseat, with the calves of my legs draped over the loveseat's firm arms at about a 45 degree angle. I wasn't quite sure whether it was the angle of elevation or the pull of gravity against my calves that was my benefactor. But my loveseat was for watching TV; the bedroom was for sleeping. Somewhere between the end of an episode of The Cisco Kid and the start of an episode of The Californian, I would gather my bedding during each morning's early hours and trundle off to bed.
In bed, I elevated the calves of my legs atop a firm, King-size pillow that I had purchased for that purpose. To enhance the angle of elevation, I first surrounded the King-size pillow with blankets. Still not convinced that its height was sufficient, I gently placed a spare Standard-size pillow at its highest point, much as a baker might do with a cherry placed to adorn a culinary presentation or as a mountaineer atop Mt. Everest might do with their country's flag.
Though I believed that the properly configured King-size pillow offered a measure of relief, the relief proved to be a "weak sister" (apologies of that term is not allowed) of the loveseat's arms. In time, I relegated the King-size pillow to a use favored by my now former wife: the dreaded "crotch pillow." To be sure, doing so was not without some benefit: the parallel placement of my legs on either side of the pillow did provide a measure of relief. Still, when the worst of RLS struck during my lengthy experience with DAWS, I adjourned from the bed to my loveseat, anxious for the anticipated relief, however brief and delusional.
With DAWS behind me, I now rely solely on pregabalin. My relief with pregabalin has been idiosyncratic, unpredictable and often evanescent. In desperate attempts to find a comfortable position, I nightly transit my bed, completing multiple orbits during my journey. From time-to-time, I cease this undertaking only so long as may allow me to reorient my position so that I may view the clock atop my nightstand. I arise from my bed, divert myself for an hour or two, and then return to my bedroom. But sometimes I am so weary with exhaustion that my return is not fully completed. On these occasions, I collapse on the bed, face down, with the greater part of my legs suspended mid-air. More often than not, I then sleep soundly for hours on end.
As an experiment, in today's early morning hours, I tested my hypothesis: I would simulate my collapse atop my bed. I did so with only my torso resting firmly in place as I lay face-down on my bed; from mid-thigh to my feet, both legs were suspended mid-air, with only flesh, bone, muscle and sinew resisting the pull of gravity against my calves. The immediate sensations were reminiscent of the sensations felt while "stretching" my legs as I stood in a doorway, offset by my arms. Only this time, there was no need to get out of bed, nor was the relief temporary. I promptly fell asleep and slept soundly from ~4:00 AM - ~9:30 AM.
Be well.
