Protein shakes

Working on the diet - I have a friend who swears by protein shakes. She said it helps her get her vitamins and also the protein powder helps with her blood sugar/keeping hunger at bay.

Can anyone give me any stories/advice/recommendations on protein shakes?

I make my own.  Are you looking for something store bought you can just drink?

Either something store bought that is not high in fat and has at least drinkable (I tried a ready made shake once and it was not very good at all). I would not mind making my own at home, either.
