My sister brought me some Bonine back from Florida a couple of years ago and I found that it worked very well and didn't make me drowsy like Gravol does. I threw out the last few tablets a while ago as the package date showed that it had expired. Does anyone know how Bonamine, sold here in Canada, compares to Bonine. I notice that the Bonamine package does not say non-drowsy. We leave in 10 days for WDW and I don't want to risk flying without something. Our 1.5 hour trip (that I can usually manage without Gravol) to the cottage this weekend took 3 hours and I was in rough shape by the time we got there.
