Hey. My mom was on valium for many years for sleep. She does not have RSD. I spoke to my doctor about going on it cause I have horrible sleep issues and no meds seem to help. Anyhow valium I guess is very addictive and most people continue to need a higher dose. So for that reason many doctors don't like to rx it. My mom was switched to ativan.
As for magnesium I talk magnesium glycinate that a holistic doctor suggest but have to order it online. Mrs D has sated that Slowmag which I have seen at CVS or Walmart is well absorbed as well.
