100 % Yes. I got mine through the #govoxbox. I tried the Vanilla as instructed with water, & after a while I couldn't take it. I gulped it down for testings sake, but was not thrilled. My employees then told me to try with milk, which defeats some of the purpose, but I figured why not. Tried the Swiss Chocolate with milk, & was happy to say that although there was a subtle after taste, it was no where near as bad.
For the mixed berry, I am going to use my nutribullet first to blend some milk with real raspberries, then mix in the berry shake in the blender cup. Looking forward to this one, as opposed to the first! :)
