Hi Bill,
Glad to see you are on the mend. It's all pretty much been covered, so I'll only add one thing... well, maybe a couple... and a boring story too...heh.
I would use a plane that was at least somewhat stunt-able.
Why? Because going in circles is what you are afraid will make you dizzy, so the best thing to do at that point is stop and do some insides and outsides or lazy 8's, which I'm certain you could still do. This would let you recover long enough to continue with some level laps. You might also consider letting someone else start the plane for you, so your not weakened or winded by the time you get to the handle. You can always take over that job once you build your stamina back up.
Also - Before your first outing, go into an empty room in the house, lock the door (so no-one can walk in and laugh their arse off at you) and hold out your hand in the handle flying position and turn in 5 second circles just like your flying. Might not hurt to have a comfy chair within staggering distance. Do it in 1 minute sesssions until it doesn't bother you anymore, try a 2 minute session, then 5 minutes. You should be good to go from there.
I confess to doing this when I came back to flying, and even flew several indoor stunts this way before I picked up a handle again. It worked like magic!!!!
When I put up that first flight with everyone watching after a nearly 14 year layoff, and started doing loops, eights and inverted, everyone was really impressed, and, I didn't get dizzy or crash. Little did they know I cheated and did some indoor "air flying" to get my feet back and knock the rust off.
Let us know how it goes and what you decide to do!
