Joe,
When I got back into this a few years back with my son, we got in the backyard and just spun around without planes. The wife came out and asked what we were doing. I told her we were practicing getting dizzy. It works.
Just spin around in your backyard (make sure the neighbors are not watching) and you will get use to it. And if you start to fell dizzy when flying, just focus on the nose of the plane.
But watch out when you start flying inverted, you may get a little dizzy when you go the other way. At least I did, but I am getting use to that now.
