Icemoose went through a stage of having all three for an evening meal and he did well on that, they say space them at first so a, you dont get too hungry and b, you need to get rid of the vitamins. When you are settled is then its whatever is best for you!
One of my favs was to have a soup, with psilly husks if you have them or not if you dont! and make a mix a mouse, now mix a mouse is ace, you can get 2 bowls out of 1 shake easily, have a puddin after your soup!!!
