Bariatric Advantage meal replacements

Hi again folks! I’m 4 days away from surgery so I’m in the pre-op diet. I feel so sick today (day 2). Thinking about the texture of my pre-op shakes is making me even more nauseous. Any advice to make bariatric advantage shakes more palatable? I don’t want to skip meals because I don’t want to mess anything up for surgery. I’m behind on 3 shakes today 🫠
