I dont know what in them I allergic to, I have tried the whey protein shakes and I get hives, the surgeon switched me to carnation protein shakes and I still get hives, I am clueless as to what it is but My body doesnt like them.. I am allergic to potatoes, and pork, so I have to be careful on that, I will stop stressing over the scale, yes I can have eggs and pureed soups, I have been eating 3 oz of brocoli and cheese soup, but I will be honest, I havnt felt hungry or full since my surgery so I dont know if I should be eating more or not, I am too afraid to get a leak to eat more then 3 oz, ugghhh this is harder then I thought it would be, cause with not enough protein Im sluggish..
