Personally, I have been on a Zero-G "Vomit comet" flight, and it *was* "frickin awesome" until about the 15th parabola, then I started feeling extremely nauseated. I'm lucky we landed before I needed to throw up (some poor shmuck paid $6000 for the flight and had to strap himself into a seat so he could throw up constantly into a bag after the very first parabola). However, I have never felt more motion-sick -- it was *awful* -- and it didn't subside for over five hours after we landed.

All this means is that OKC's match algorithms suck: there's only a weak correlation between match scores and real-world compatibility (like with every other dating site).
I opted for PRK instead of Lasik for the following three reasons: (1) there's no flap with PRK, so no loss of structural integrity; (2) PRK reportedly causes fewer problems with dry eyes (because you're not severing the nerves within the cornea, just cutting off the nerve endings); and (3) PRK removes less of the cornea than Lasik, making a later "touch up" operation more of an option.
Recovery from PRK was brutal -- for two weeks you can't see anything ("I see men as trees, walking") and it feels like someone has poked both your eyes with their thumbs. Five years later I still have frequent issues with dry eyes -- primarily, I often can't really open my eyes when I wake up until I have put drops in, they're very painful otherwise. Getting salt from the Dead Sea in my eyes recently was excruciatingly painful -- more so than for normal people. I don't have halos at night, but if my eyes are dry I get some glare. Would I do it again? I think so -- life without glasses is awesome, and my vision is better than 20/20 now. I can live life without glasses for the next 10 years, then only need them while reading once presybyopia sets in. But the dry eyes almost make me say no, maybe it wasn't worth it. I go back and forth on this. And I miss the style factor of wearing glasses, to be honest.
