Well done! remember that we are 2D animals slowly evolving. 3D motion is a bit of a stretch but you will soon acclimatise. When the fight or flight mechanism kicks in through exitement the chemicals in brains and guts conflict. It is well worth persevering. Not too wise to fly for first time ever in recent weather due to risk you may be put off. Not everyone is into the roller coaster but you will soon be hankering for more....
