Airbus Pilot,
I had same problem for first 5 flights. It did go away naturally.
I found making sure I got enough air in the cockpit helped, even if the FI is a little cold
If it doesnt go away naturally there is a good drug that the RAF use. One of my mates has severe problems and this has helped him. I will try to find the name for you.
Even though my sickness has gone away for General Handling exercises still feel terrible after Aerobatics. Still love doing them just the after effects yuk .
Good Luck
