I am three days post op and can't stand any of the Protein powders I have now. My dad has regular whey protein but it has soy and milk products in it. If I mix them with Water can I drink that? It has milk so I am not sure I am allowed I thought we had to stay away from milk for the first week.

Also my stomach is growling n I am starving. Is this normal???

yes it's normal!

Is it unflavored whey? If so you can put it in anything sugar free. I put it in crystal light, Hawaiian punch, poweraide zero, etc. It's good in soy milk too. Soy Slender is sugar free and it's good.

So it's ok in my first week to have a protein powder that has milk and soy in it as long as I mix it with water right??

My Doc gave us all proti-Diet for post op, it is clear in 8ozs water and 15 grams of protein and tastes like crystal light. GET SOME!

You can mix it with water of any sugar free drink that you like. Experiment. There are a lot of flavored mix in things that you mix with water that you can use to make the protein taste better.
