Protein Powder Question

One more physician visit and then I'll be doing the insurance waiting game. My surgeon suggested a protein shake recipe using sugar free protein powder, but I haven't been able to find a sugar free powder.  Anyone, know of a sugar free brand that I can use and half way enjoy the taste?? 

isopure zero carb unflavored. I was afraid of it at first that it would make my drinks thick and it doesnt. This morning, I put it in with my coffee and i had no clue it was there. I put it in water with strawberries or raspberries and shake it up and its fine. Or, i put a teaspoon of peanut butter with some soy milk (which also has less protein but less sugar than skim or skim plus). You get 25grams of protein with each scoop.

I use Isopure Unflavored Zero Carb protein powder. It has 110 calories and 26 grams of protein and no sugar. You can order it online or check with GNC or the VitaminShoppe.

ISO 100, Isopure Zero carb, Isoflex are all sugar free.  The first 2 are splenda based and the other has different chemical sweetners.

The tastes are tolerable.

I love the Optimum Nutrition Double Rich Chocolate powder.  I mix it with almond milk.
