Misty -- when I was looking through a bodybuilding magazine tonight, I saw an ad for something called Whey Fruity -- high protein, no carbs, and sweetened with Splenda. The nutrition info per scoop is 105 calories, 26g protein, 0g carbs, 0g fat. The ad says: "Whey Fruity tastes exactly like a delicious fruit-flavored kid's drink" so I thought maybe it might be a bit of a change for you from the Isopure? It sounds like Kool-Aid.

I don't know if you've tried it -- I haven't -- but they're offering free samples if you call 1-888-828-8008. This is their web site:

If anyone tries it, I'd be interested in a review.
While we're on the topic of protein, I made batch of Mel's protein banana nut muffins tonight and they're awesome! Only 120 calories each, with 12g of protein and 12g carbs per muffin, no added sugar. If anyone's interested, I'm sure that Mel wouldn't mind me posting her recipe.
