This has no doubt been discussed before but I haven't really used this site much yet and so haven't found it.
My PD is reasonably controlled during the day but I dread going to bed! As soon as I get in to bed I am uncomfortable, mainly because of my leg which has the tremor. The tremor gets less but the whole leg feels tight and uncomfortable no matter where I put it. When I finally manage to get to sleep it is only for 2 hours max and then I HAVE to get up and walk around as the leg feels like a dead weight. So then the whole thing is repeated - I can't get comfortable and eventually may sleep for another 2 hours! This means I am up several times in the night.
My neurologist gave me a 50 mg dispersible Madopar to take when I woke in the night and recently I have had to take 2, one at about 2 am and the second at around 5 am. I also take Madopar controlled release at around 8.45 pm before I go to bed at around 10 pm. This helps a bit but I wondered if anyone else had this problem and how they deal with it.
