restless legs syndrome
"I was diagnosed with Restless Legs Syndrome about 4 yrs ago and was prescribed Mirapex.  My symptoms were so bad I wouldn't sleep for days and was non functioning due to being sleep deprived. The doctor put me on 0.25mg every evening but my RLS was creeping into daylight hours, so I was prescribed 0.25mg twice a day.  That did the trick and it has saved my sanity.  I no longer have any symptoms of RLS --and as a side note - I have no side effects either from the medicine."
