I also take TASMAR 100 mg 3 x a day. Like you I get sleepy about 30 to 60 min after taking. I don't fight it, I lie on my bed and catch 40 winks. It has just made the world of difference in how I feel -- smooooothed me right out. The rest of the time I have lots of pep. I am have my liver checked every two weeks. Take SINEMET CR and also MIRAPEX at night for RLS. Good luck. Eldon Green, 70/5 Tampa Bay, Florida
