Is There A Certain Protein Making Me Nauseous

I am over an a year out after my Mini.  About 2-3 months after I began having problems getting nauseous after drinking milk, eating yogurt and eating a protein bar. So I thought I would try Soy Milk and Almond Milk, same thing. Now I can eat cottage cheese and other cheeses just fine. Oh, and no cream cheese based recipes! I really like protein smoothies but I can't. Is there a certain protein that I am having a problem digesting? Any ideas?

This is very common. Dairy intolerance is something many go through.  This may improve in time.  There is a special protein made especially for bariatric patients.  It's called Unjury (unjury.com).  I have actually met the developers and they are sincere in their product.  It is a fine grain whey protein that you may like. 

Give yourself time.  See how things go.
