I was diagnosed in 2000, aged 64. I count myself lucky that P seems to be slow developing and I can still drive.
I take my meds(Stalevo) at 5 spaced intervals during the day. First around 8am (with 1 Requip XL), the last at any time between 9pm and midnight. I retire at around 1am to 1.30, having dozed through various TV programmes.
I usually have to visit the bathroom during the night but, here's the thing, I don't need to take any medication during the night.
When I fully wake up around 7.45 I don't have the rigidity or slowness of movement which I get during the day when my meds are fading. Before the first meds have taken effect I am able to sort out my meds for the day, put them in a little pillbox; I can walk down the stairs and greet the dog; I hold my cup of apple tea without tremor; I can hold a pen and do a crossword or Sudoku or other puzzles. But after the first Meds begin to wear off at around 10.30 I can become almost comatose until the next lot kicks in. I've even got into the shower feeling OK then been almost unable to dry myself afterwards.
I would be interested in hearing about other people's experiences. I note that some people refer to taking meds during the night. Is it necessary?
