Shakes are fine just watch the sugar. Even really good all natural ones hide sugar. Not sure about Isogenix but Jay Robb is good. I tried Isogenix once and couldn't stomach them. I liked the Jay Robb ones much better. Also with all your travels have you ever thought of trying the patch? There are a couple of threads on here you can find and see how everyone is doing. There are a lot of happy campers here.
