Haven't received a date for surgery yet, but trying to be prepared and find some protein shakes I can tolerate. I have had trouble with these before, I.e. nausea. I tend to regurgitate these as soon as I drink them. Don't think that would be good post op. I have tried sipping, disguising in foods ( which is a little more successful), but post op is supposed to be only liquid. I have tried a number of different types, but always with the same results. Does anyone else have this problem? I tolerate yogurt well. Could liquified yogurt be a solution?? Any thoughts would be helpful!!!
