When I did the Zero-G flight back in September '04 on G-Force-One I intentionally did not take any anti-nausea medication. I wanted the experience to be just me and my body, untainted in this new environment. I did yack on the third or fourth micro-g parabola, but not much, and I probably could have crawled back out to join the rest of the bunch for the last couple of parabolas.

Tom is right in that it was the cycling back and forth that did it for me. When you can feel your intestines settling a bit into your pelvis on the pull up, and your hair pressing down on your scalp, it does get to you (I've developed good proprioceptive sense through biofeedback). I was absolutely undisciplined and looking all around the cabin, which they tell you not to do. I've been told that they make folks lie down now, and that has cut way down on the incidences of illness.

Next time around I'll be ready. My body knows the experience, and remembers it. When I went to the Cirque de Soleil show Kà in Las Vegas with the Lunar Commerce Roundtable I was getting flashbacks during one scene in which acrobats are doing freefall maneuvers on a large rotating contraption. I wanted to get onstage and do it too because my body craved that micro-g experience. I have to stop myself from going to tall skyscrapers, riding the elevators to the top, and then doing a jump as they start descending to get a brief instant of freefall.

If you get the chance, do it. It's not about the vomitus, it's about the joy and wonderment that the body feels in freefall. It is incredible. Sans pareil. Il n'y a pas de mots pour le décrire vraiement, ni en anglais, ni en francais.

Do it. Do it. Do it. You will not regret it.
