I came across some crystalline chloral hydrate and dissolved about 200 mg in a half-cup or so of water. When I took a sip I immediately felt my face flush and my vision darkened a little. It's been about 15 minutes since then, and I've finished drinking it all. I would compare the high to that of alcohol, but I am much more clear-headed, and there are no unpleasant physical effects at this point. If anyone has the chance to try this out, I would recommend it (though do your research, it is not a very safe drug).
