I found that the more specifically you can communicate with your doctor about your symptoms, the better the results. Example: rather than telling him/her that the RLS is "bad" or "terrible", etc. say " I have to move my arms or legs every 5 seconds for as long as 2 hours at a time". They really GET this!
When I finally communicated to my doctor this specific description of my symptoms he finally prescribed an opioid. And I finally slept. Try it!!
