Be careful with the decaf coffee. You need to talk to your nutritionist or surgeon to see when you can start drinking it after surgery. You may have to wait a short while because of the acidity. My surgeon told me I could go back to regular coffee 3 months after surgery, but again, speak to your nutritionist or surgeon about this first. Also, ounce for ounce, sugar free Jello, sugar free popsicles and protein drinks (low carb) also count towards your daily fluid goal.
