restless legs syndrome
"I rated this based on how the medicine worked in the beginning. HOWEVER over time my symptoms became worse, would happen during the day, and I had to take the medication around 6pm to be effective by 10pm. 

I am now on a low dose of Tylenol 3 that I take 30 minutes before bed. In the three months I have been on this regimine, my daytime symptoms have disappeared. I have not had to increase dosage or felt the need to take the medicine at bedtime (major concern of Drs is becoming addicted to anything with codeine/ opiate). 

Also tried gabapentin. It was a nightmare."
