Hello there, a definate yes to this link with eating. I am now in my 8th year of parkinsons, diagnosed when I was 29. I do not eat during the day at all so my day is;

06:00 1xhalf sinemet cr, 2x62.5 madopar and 2mg of trihexyphynol hydrochloride;
10:00 1xhalf sinemet cr, 1x62.5 madopar,
12:00 1x62.5 madopar and 2mg of trihexyphynol hydrochloride,
14:00 1xhalf sinemet cr, 1x62.5 madopar,
18:00 1xhalf sinemet cr, 1x62.5 madopar and 2mg of trihexyphynol hydrochloride, 19:00 after this time I can eat anything but tighten up a little
21:00 I take a 2mg zopiclone tablet along with 2mg of trihexyphynol hydrochloride plus a medicinal glass of whisky :-)
21:00 – 02:00 if I wake in the night I go and have a protein full snack, I am rather partial to cheese and crackers

The only quirk is that the madopar and the trihexyphynol hydrochloride must be disolved in not too much water (100mls). For the best effect trihexyphynol hydrochloride appears to act optimally if left to soak for 30-60 mins but it is a tablet that does take some getting used to.

For me the crucial feature is not to take any levadopa for the 12 hour period between 18:00 and 06:00 to allow the body to rest and start from scratch each day. Routine is everything...

My general condition, if I stick strictly to this routine, allows me to lead a relatively normal life with virtually no off periods despite the Parkinsons generally I lead a normal life while this routine is adhered to.

Of course everyone is different...
