I am almost one week out (3/24). Water hasn't been an issue. It takes me all day to get the 60oz they require. I have now started adding in Propel and V8. Didn't realize I could do V8 but it's on my paperwork. It's been a welcome relief.
I have been struggling with getting the Protein. DR wants 70grams a day. I get so full from one shake that it will take 10 hours before I can even consider drinking another. I started exploring other options to get it. chicken broth, cream Soups, yogurt (never been a fan of Greek).
