Well I found something that does not agree with my new tummy. Premier protein strawberry flavored. I took about 4 sips and my tummy felt sore and now I'm in the bathroom an hour later. Tmi.

For 2 or 3 weeks after surgery my tummy would not tolerate Premier Protein shakes of any kind. I used these protein drinks before surgery & was just fine with them. It was about week 3 before I could drink them again after surgery. I drink one almost every morning when I get up & I switch between the chocolate & strawberry. I heard the vanilla was awful but I understand the new vanilla is good. They also have a new flavor. I think it's some sort of berry flavor. I'm going to check Kroger's because they are supposed to sell them individually. I don't want to buy a case & find out I hate it. I hope your tummy gets past it's issue with Premier Protein shakes.
