restless legs syndrome
"I have had undiagnosed RLS for years and had huge horse pills Gralise to take and so many of them with a high fat meal which made me gain weight.  Horizant is so much better just one pill at dinner time and I get my rest. Glad Dr explained to me that each 600mg tablet is actually equivalent to  313mg Gabapentin and not to break it but swallow whole with food."
