I have RLS too and had it for 20+ years. I was a runner and about 20-21 years ago I stopped running due to bad knees. I gained weight. I began having leg problems that later I found out was RLS. 5 years ago I had open heart surgery and lost 34 pounds, my RLS disappeared. By last year I had gained about 12 pounds back and my RLS returned. Subsequently I lost about 15 pounds and my RLS disappeared again. So, the people talking about back pressure or pressures may have hit the cusp of the problem. When I was heavy I had problems, when I lost the weight I also lost the RLS symptoms.

I gained weight while on Mirapex. I believe it is due to the medication.
Unfortunately I’m still on the medication.
I gained weight too, and now that I’m off Mirapex I’ve lost 15 pounds and my eating habits have returned to the way I used to eat before Mirapex. I posted a new piece on what I do and take to handle insomnia without Mirapex. I hope it works for you, too!
