I realize this is an old thread, but I have just had an eye opener. I was/am an avid cruiser. We are now on our 90th cruise. I was sleeved in July 2016. Six weeks later I did a cruise without incidence. Now, I am 6 months out and on a cruise, having a lot of sea sickness. I did not realize what it was until day 3. I never had sea sickness before this. I took Bonine, which helped relieve the symptoms. I don't understand what is different now. The size of my stomach shouldn't matter, should it? This could put a serious damper on future cruising, which would make me sad. Is there a chance it's only temporary? Sent from my SM-T900 using the BariatricPal App
