Hi again Barb - I tried taking a little (like you half) but that is what kept me like a zombie all day. I have a problem because so many drugs make me sleepy. Sinemet always does and so does Tasmar. If I take a few quick zzzz's tho I am alert again. My Neuro always says, It's your body - only you can tell what works so he gives me carte blanche to experiment. I've taken my meds without the short nap and I could easily fall asleep right now while drinking coffee and typing. It sure is true that what works for one of "us" may not work for another. helenjc
