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.

My understanding is that this only works for specific type of focal brain damage. I.e. if you had gross denial that you have a paralysed limb. I never heard that it e.g. relieves delusions in mental disorders, and i'd think everyday self deception is less similar to focal brain damage than to mental disorder.

Yeah, it'd be shocking on multiple levels if it did anything but induce vertigo. But it was fun trying, and the videotape criticism gave me a reason to do it.
