Mia and Colleen, unlike the other methods (bonine, seabands) you can put the ReliefBand on once you're sick and within several minutes you will feel better. It interrupts your equilibrium and keeps you "on balance." I do not wear it all the time when cruising because the pulsation can irritate your skin after hours of wearing it. Not a big issue, though. I was getting very ill on VOF after Dramimine, Ginger pills, etc. and could not overcome it. We broke down and bought the watch, and within 15 min. I could not believe the nausea went away. The last night on VOF we encountered a dreadful storm, with lots on crashing and thrashing and I wore it all night. It worked!! As you can see, I am a reliefband devotee :D :D :D
