HI Marjorie,
     Have you tried good old-fashioned Benedryl for your allergies? It is
an
anti-cholinergic easily tolerated by many PDers. Also thought to have a
therap[eutic effect on PD symptoms.It is prescribed often by Emory doctors as
adjunct
therapy to Sinemet,for mild sleep aid (in lieu of harsher prescription
sedatives)
You can buy it in liquid form & also in generic form. It's very inexpenive -
Using
liquid form also allows you to tritrate as needed.
     I use it at night for sleep and like it much better than prescription
sedatives.
