SORRY for yelling HELP but I need a list of cold meds which I can take without causing problems with my PD meds. I have a heavy chest congestion and its causing caughing. I know that ROBITUSSIN caugh suppressent is a definite NO-NO so what can I use. Of course I am drinking tea with honey and lemon and chicken soup and rubbing lots of VIX but really I need some meds. Any help ??? Joyce
