I'd be interested to know if they helped with nausea from a sv, too. I'm so worried now that it's getting colder here. This time last year my son got a sv and then I got it, my daughter got it, then I got it again! I'm already having anxiety attacks about a trip to visit family out of town. I'm definitely taking my sea bands, I'd forgotten about them for the car ride. My problem isn't motion sickness, it's anxiety over being stuck in the car for hours, possibly in lots of traffic, with two small kids during sv season, etc. Like others said, even if it's a placebo effect, it works because the nausea is all in our heads anyway, right?
