Today and yesterday I tried it essentially as Eliezer described: put a glass of water with ice cubes in the freezer to cool, prepared my syringe (bought to feed a dying ferret), laid on my side, and set up my camera across from my face. I turned it on, inserted the syringe, and injected 10ml of ice-water.

The result both times? Substantial vertigo within 5-10s, lasting ~5m. (No feelings of vomiting, although I ride rollercoasters for fun and have gone skydiving, so this may not generalize.) During the first minute, I reviewed my beliefs on the usefulness of modafinil, whether I should accept an O'Reilly ebook offer, and then my general beliefs of atheism/materialism/determinism/utilitarianism/left-libertarianism. I did not find anything to object to that I was not already well aware of (eg. my cost-benefit analysis for modafinil may be off by 3 hours).

I reviewed the recordings 2 hours after the second try; the recordings matched my memories, with nothing worth noting.
