I couldn't bring myself to just do the whole shot at once, so I started out with a little girly sip. And the truth is it's not that bad at all. It tastes like milk, just slightly more sweet. And mentally, just slightly more making me want to gargle with Clorox and assume the fetal position while I question my life.

Also, have you tried baby formula (just to give the other side a chance)? -- it's like poison and I cannot believe any child can choke down that stuff. It is the most bitter taste on earth, I swear!
The only thing out of all that that I ever tried was natto, which is (I think) just fermented soybeans. It wasn't particularly tasty but not horrible either. It's supposed to be real big in Japan. Different strokes for different folks I guess.
