I made the strawberry milk. Pretty tasty!Try it with the chocolate milk, then after a while you'll realize you're still drinking egg whites. Then re visit drinking them plain and see if it has a psychological effect still. I too thought it would be gag inducing, but it wasn't because I already rationalized that I have been drinking them anyways... Regardless if there was other ingredients added.
Only thing is, I find the egg whites a bit harder to chug than protein shakes. I can just knock protein shakes back, but the egg whites I have to sip a bit more slowly.
