What do you do for restless leg syndrome and periodic limb movement disorder. Also have Fibromyalgia.?

I was diagnosed with Fibromyalgia 11 years ago. Prior to that I was diagnosed with Hashmotos hypothyroidism, an auto-immune disease attacking the thyroid. 3 years ago, when trying to DC a med for Fibromyalgia, I learned that I had developed Essential Tremors. Now I've moved on to Restless Leg and Periodic Limb movement disorder. I'm dealing with the central nervous system here, and wonder if I don't have Chronic Lyme, although all tests have been negative. I grew up in the woods of a lyme infested area of PA. I'm dealing with it all, but the lack of sleep associated with Fibromyalgia and the waking from periodic limb movement disorder and minor Sleep Apnea are reaking havoc with my life. Anybody out there dealing with the same mess??? I'm all ears.
