I have been reading questions posed in the past about the problem of a dry mouth and wondered if anyone had found a solution to this. My mouth is very dry and I also have an unpleasant taste which seems to transfer itself to my food. I also have a sore tongue and mouth ulcers. The lack of saliva also causes a build up of mucus in my throat which is very unpleasant. I am on Stalevo, Requip and also medication to control pain in my back and shoulder. I understand from my GP that medication is the cause, but am reluctant to stop any meds in case it affects my Parkinsons.
