@mamacita My Vit D wasn't deficient before and is still very much within normal range so not at all sure why the Vit D controls RLS. Both RLS and PILM complicate the whole sleep thing. From what I understand, RLS occurs when we are just falling asleep. I wonder if your sleep Apnea has you "falling asleep" frequently through the night, especially now that your machine is broken. You might try the Vit D and see if that helps calm your legs. It certainly was an easy solution for me. I had MDs prescribing medications usually used for Parkinson's disease and they made me so sick.
