The best option is : Let her fly.
Teach what and how the airplane responds to "her" control inputs.
Do it gently, and it will all be over before you know it.

But also know : Air sickness is for everybody.
I flew between 50 and 100 hrs a year in all kinds of stuff.
From Ultra lights up to and including the F-16.
Never got airsick. Did not know what it meant.

One day, our CO handed me a ticket to Farnborough (UK) as a passenger on a BAF HS. A small trip of about 45-50 minutes.
As usual, LOL; I fell asleep soon after boarding.
Half way over the channel, (Belgium to UK) I woke up, as sick as I had never been before. Man, man, man, I could crowl under my seat..... and was sick the rest of the day.
In the evening we had to board for the flight home. I walked up those stairs with lead in my shoes.... This was gonna be bad.
Seated, and once airborne again, I recovered as if nothing had happened at all.
Very pleasant flight home, and when driving home, I wondered ; Hey what happened today? ?
