restless legs syndrome
"The medication worked when I first started using it.  I had a few side effects like dizziness upon standing and slightly blurred vision.  After taking the medicine for over two years, the effectiveness to my RLS has waned considerably.  I rarely have a night when I can sleep or even sit in a chair and watch television without my legs jumping.  I am constantly having to change positions or get up and walk or basically try anything to alleviate the problem.  Which doesn't always help."
