Drew: I've been wondering about dehydration being a PD trigger. My husband pointed out the fact that I don't drink water the way most people do. I don't drink alcohol and never have. My daily liquid consumption would average 8 ounces of juice and maybe 8 ounces of other liquid like tea and pop. I drink a small glass of milk on occasion. I don't think I remember water being placed on the table at mealtime when I was growing up. My parents drank gallons of tea. I did not. Before PD I played a lot of tennis and back packed a lot of miles. I was never very thirsty. I'm trying to do better but the horse is already out of the barn. My regards to your dad and mum.
