Ready made protein shakes which one is best post op?

Most nutritious, low carb little or no sugar best tasting protein shake, ready made.  Which one is your favorite?

Hi, I have two that I like:

pure protien- 23 grams protien, 1 gram sugar- 120 calories

and 

Atkins -15 grams protien-1 gram sugar - 160 calories

those are the only ones I have found that I like. 

I cant do the powders are all. They upset my belly. 

I personally went with the powder and added it to diet cocoa.

This is what worked for me.

My favorite are Chocolate Premier Protein (30g protein) and Vanilla Creme Muscle Milk (20g protein)

I love premier. I buy the vanilla and the chocolate. They have strawberry also. I find the chocolate and vanilla to be my fav's. The vanilla and even the chocolate you can put in a blender with ice and add diff SF syrups to make a variety of flavors. Only 160 cals for 30 grams a protein.  3 grams of fat, 4gms of total carbs and 1 gram of sugar. They can't be beat. Usually start my day out with one!

I love the Premier Protein shakes and each one is 30 grams of protein.  They are ready made and tasty.  My favorites are the strawberry and chocolate since they are more flavorful than the vanilla.  I have seen recipes to enhance the vanilla but I have not tried them.
