Paul, I used the scopolamine patch about 5 years ago before my PD diagnosis. I was on a 30 day sea test of a system. The patch works, but it has side effects and should not be used more than 3 consecutive days per the label. Side effects include blurred vision, dizziness and in some cases mild additive dependency. If you develop dependency, you may experience nausea and dizziness as you come down off the drug. I did experience blurred vision after 3 days, but the drug did work. I developed a tolerance for the sea motion by the time I experienced the side effects so I no longer required the medication. Although I wasn't nauseous, I did have an unsettled stomach for the entire trip. This seems to be common in people that are prone to motion sickness as a result of an over acid stomach. So take some antacids with you. Enjoy your trip. Phil Gesotti 49\46
