I've had PD for many years , and nausea has always been an isssue. I was OK on sinemet alone but since i have to use mirapex now, i am sick every day. Can't sleep because of stomch pain and nausea, i go to bed and just lie there in a half-sleep and have bad dreams because of the nausea. I wish that there was something effective for nausea. I've taken the drugs that are prescribed for nausea, but they don't work for me.
