All of that said... I really DO like the "lemon thing". It works pretty well for me if I'm mildly "off". If I'm WAY off then there's no hope, really... lol... but in general I like it.

I do one lemon in about 8 ounces, but then I do a second glass of it. (I kind of shot gun it though over the course of about 10 or 15 minutes.) I don't know if I could take a full two lemons at once.
