Preop...need help with protein by lunch time

I know everyone is sick of reading about protein powder but I really need help.  Yesterday my doctors office called and said they had a cancelation next week and I needed to start my preop diet today.  I had one packet of Jay Robb vanilla and it tastes like a$$.  It was way too sweet for me, the smell was horrible and the texture is gagging me.  I have to find something by lunch time and my options are GNC and Walmart.  Can you suggest something for short term to get me by and also something I could order for later?

Pre-op I loved the Pure Protein Ready to Drink shakes mixed with a little milk

Ready to drink premier nutrition protein shakes. 30g of protein. the chocolate one. I think its sold at GNC. I have also seen it at costco.
