I've had RLS for several years and it has disrupted my sleep so much that I end up sleeping through the next morning. Sometimes I feel like I'm going to jump out of my skin. Walking helps RLS temporarily, but my neuropathy (burning feet) can't tolerate much walking. Recently had "iron studies" done, and it was found that my Iron % saturation and my ferritin are so low that iron infusions are recommended. Iron deficient anemia causes RLS. Will give the infusions a try, though I'm skittish about it, thanks to a bad experience with IvIg infusions.
