restless legs syndrome
"I have had restless legs syndrome for years due to iron deficiency. I took Sinemet for about a year and it seemed to work great for me. However, I could not take the full or even half of the dose because it really made me feel drowzy the following day so I would break it up and take a very small piece of the pill. Also, if you don't go to bed after taking it and stay up for a while, it can have the adverse effect on you. Makes you really sleepy, but make your restless legs symptoms worse. Good Luck!"
