Well Emma, how about a medical opinion. I'm an ICU nurse and usually I'm REALLY skeptical about alternative medicine, but we went on a cruise in '98 and I changed my mind!! When we hit a little rough waters and I started to feel preety queezy, I went to the on board store for some dramamine. There was a new staff member there who convinced me to try the seabands and I have been hooked on them since!! I never go on a long car ride without them and they are already in my bags for my up coming cruise in June!! I highly recommend them to anyone who wants to have a great time without the side effects of drugs. Ellen
