I haven't found a protein shake that I love either, they all either seem to have a weird chemical flavor that I just don't like, or else they are too sweet for me. I drink them anyway because I know I need to, though! I've tried Unjury, EAS, Boost Glucose Control, and Designer Whey. I recently went to MOM's (My Organic Market) in Columbia, though and they had a whole shelf of sample packets (one serving) of lots of different kinds of protein and meal replacement shakes. I didn't get any at the time, but I do plan to go back and try some others.
Something I did find that has been great is from Shaklee....a direct market company that my sister is a representative for. They have a great reputation for high quality nutritional supplements and other products for healthy living. They have an unflavored instant soy protein mix that I really like. Two tablespoons of the powder has 16g of protein and no sugar. It dissolves quickly and can be used in baking and cooking too, as heat doesn't destroy the protein like in other powders. It's a little expensive, but worth it to me. I've used it in shakes, puddings, soup, etc. It is called "Instant Protein Soy Mix" and can only be ordered through Shaklee or a Shaklee representative. You can check out the label and recipes at:

One note: my nutritionist did say that whey protein is usually better tolerated than soy, as soy can sometimes cause more gas. I really haven't found that to be the case, but just thought I'd mention it!
