Hi. I have RLS. I have had it for over 10 years. I also have fibromyalgia, rheumatoid arthritis and sjogren's syndrome. I am on several different medications. My iron has never been low. My thyroid is normal. I have been on Klonopin before. Did not work for me. I am now on Trazadone. It is working for me. The best thing is to be able to get some sleep, which is hard when your legs ache and you feel a need to move! If you are still having issues, I would try having a sleep study done. I would also try a different medication if you aren't getting relief. Many doctors will tell you with RLS or fibromyalgia or other types of diseases for which there is no cure, that you just have to live with it. But you don't. If that is what your doctor has told you, you need to find another doctor. I have gone through several doctors before I ever even got my diagnosis of fibromyalgia. It was a sleep study that gave me the diagnosis of RLS. Do not give up hope. I also was very low on vitamin D. I take supplements now.l I think it is helpful, too. Hang in there. You can get better relief than it sounds like you're getting.
