I experienced this for the first time ever. I always felt the sway after getting back to land, but this time I was in the airport trying to read before we left for home. I was sea sick, legit sea sick on land. I ended up taking a Bonine and it settled the feeling down. In bed that night I felt like I had the spins. By the next day I was back to normal, but I really felt like garbage the first day back on land. I kind of attributed it to having 4 days at sea. Normally my cruises only have 1 day at sea at most, but we had to switch ships last minute due to our ship delayed in drydock, we got a new cruise leaving the same day but it had 4 days at sea. I really feel like that had something to do with it. Have to see how I feel after our next cruise which only has one day at sea.
