Re: does anyone else get LAND sick
For some people, this is not unusual for a short period of time. It could also be an indication that you have an slight ear infection or other problem affecting equilibrium. If it does not subside, or is now at a level that is something more than a minor concern, a trip to the doc to have it checked might not be a bad idea.
As far as the normal side of things, I once spent a year going to sea for weeks at a time. After returning to port, I sometimes felt as you are describing for several hours - I was just so used to walking about the vessel compensating for seas all the time, that my body had to get used to a solid surface again. It always went away and there was nothing physcally wrong.
