Does anyone experience a dry/itchy throat at night while sleeping, which causes one to wake up and start coughing? My wife, 50/7, started to experience this problem about 3-4 months ago. Her Neuro says to see her primary care MD, that it is not caused by her PD. But he has been wrong before. She hasn't switched meds, so I can't link the coughing to that. v/r, Nick
