Protein Shakes Making me feel Sick.

I dont think it is a lactose intolerance, my husband made me a broccoli cheddar soup and i havent had any problems with that. I have no idea what it is. I will have to consult my Dr. Switching to pureed on wednesday so hopefully ill only have to have one a day.

The first few months post op the protein drinks made me feel pretty bad.  I tried many varieties.  Now I can drink one a day of just about any brand but do prefer protein isolate.  I still feel a little queasy after finishing but the feeling goes away within 30 minutes or less.  It doesn't matter what I mix it with.  I'm a year out and don't seem to have problems with any food other than the protein drinks and bars.
