WTF, I bought it for 1.99 oer bottle and it was no more than 10oz's. I looked but didn't see any bigger bottles of it. It has 4 carbs, 1 sugar, and 13 grams of pro.
I could be wrong, but I think the carb countdown yogurts have aspartame or sucralose in them (or some sort of artificial sweetener). I think that would explain the aftertaste, if the aftertaste you're talking about is what I think it is.
lol, When you first posted this thread, I thought you were talking about the little yogurt drinks. I went back the other day and found the 1/2 gallon milk and chocolate milk. I love this shit!!! I usually mix it with my protein shakes now. Or I might have a glass for dinner instead of water.
