restless legs syndrome
"I have severe RLS Not only do I have terrible restlessness in my legs back and shoulders, but pains in my legs and back. 
In the past I took gabapentin and tramadol which barely controlled the symptoms. 
After taking one pill at 5pm I experienced 100% reduction of my symptoms. This has been a miracle drug for me. 
It is basically a form of gabapentin which is absorbed and is available in the bloodstream. 
Brilliant!"
