Besides not sleeping, I am having trouble with gastroparesis whereby motility of the gut hinders it going through the digestive system. I was prescribed 10mg. (it is sent from Canada) and I take it 3 times a day. It works sometimes. What other medications might work? I eat very small amounts over a day's time, which unfortunately has caused weight loss. Does anyone else have digestive issues? I have had PD over 13 years when I was first diagnosed. Having this situation makes it difficult to eat with the family.
