I Have Fibromyalgia And Restless Leg Syndrome. I Am Already

I have fibromyalgia and restless leg syndrome. I am already taking 2 mg ativan, 10 mg of ambien, and pramipexol. It's still an issue especially when relaxing at home and sleeping. What can I do to get a good nights sleep. I've tried Lyrica and it was wonderful, but I gained 40 lbs on it and I already weigh 237 lbs. so it puts me close to 300 lbs when I take it.
