I remember from the BBC series "combat pilot" that one of the pilots' started getting airsick so they sent him down to a med section at Farnborough? for desensitising treatment. does anyone know if it is avail to the civil population?
Neil Williams said that when he felt his G limit reducing he'd come back down and have something to eat (something more substantial than a Mars bar).
there is also a degree of getting used to it plus fittness as well I think, from what I believe if you are shorter and/or have some muscle you can cope with g much better than others.
