I love the choc mint! But, I don't like the chocolate one. Strange isn't it.
I always make my shakes with iced water. I fill up a small bottle with water, put it in the fast freeze compartment of my freezer, and then after aroudn 30 minutes it is freezing cold and slushy, perfect for making shakes as I like them.
Also, I ALWAYS drink them with a straw. I can't stomach drinking them from a glass, makes me wanna chuck.
