Just say a message responding to Pat's question on melatonin. Someone said that it had helped their PD person and they had not seen any adverse reaction. Everyone reacts differently I think. The newsweek article talked about different responses a little. I tried it for awhile and I did not see they relief I was looking for. My problem has never been falling asleep-I wake up in the middle of the night and stay awake for several hours, sometimes I just get up and don't go back to sleep. When I took melatonin I think it did make me go to sleep faster and I did sleep harder until I woke up. It never helped with this problem. The Newsweek article said that some people felt groggy in the morning after taking it. That was me. Partly because I had been awake several hours during the night, but it was even more than normal (the groggy feeling that is). Someone on the list suggested I try a timed release version. I have not done that yet. Nancy Walker [log in to unmask]
