Hi. I was disappointed that you had no responses to your post, as I was hoping to get some useful info. Sorry that I can't help with personal experience.
I currently take 5 x 100/25gm Madopar tablets per day, at between 3 & 4 hour intervals, usually 8 am, 11.15am, 2.30/3pm, 6.30pm & 10pm and another 50/12.5 tablet at about 4 am when I wake up with really stiff neck and can't relax it. Usually in about 30 mins it eases and with luck I can get back to sleep. My consultant has told me that if I find I need to take these even more frequently he would add Entacapone which would increase the duration of benefit of the Madopar. I think he said it only adds about half an hour. Alternatively, Stavelo contains it in one tablet (= Sinemet and Entacapone). If I do want to go this route think he would prescribe Sinemet instead of Madopar for a while first, to establish/check a beneficial dose, before going onto Stavelo.
All in the future, distant, with luck! My main problem is gait initiation and poor balance, which are always pretty bad regardless of taking meds. I do seem to have had to increase to my current dose level rather more quickly than I expected - started Madopar about 14 months ago, when 3 x 50/12.5gm tablets daily seem to do the trick. I now find I get a really stiff uncomfortable neck when need next dose! Consultant thinks I use dopamine up v fast as I have, or try to have, a very active life-style - amongst other things, I'm a keen cyclist, but can only do about half the distance that I used to, and am useless the following day!
Hope that all makes sense. Best of luck with next appointment.
