You got lucky.  Me too.  I could practically chug liquids from day 1.  Protein fills me up fast.  Good way to be.  Easy to stay hydrated, but still limited on food intake.

Or vice-versa: add instant coffee (and milk, if you want a thinner consistency) to the vanilla protein drink. It took quite a bit of the instant coffee to get the taste to my liking.

I track everything on MyFitnessPal so that I can make sure to hit my minimum grams of protein and avoid hitting my maximum grams of carbohydrates every day. It's not going to be accurate to the exact calorie count, but it gets pretty close as long as I am weighing and measuring my food whenever possible. 

Ask your Dr, every surgeon and nutritionist are different. Mine is total carbs but I do not count veggie carbs.

I am trying to get my 100-120 grams of protein as well as 100 grams of carbs in each day...  just wondering how many of you post-surgery continue to count grams each day or do you just "know" that you are getting close to the right amount?  I still watch my 64 ounces of water... but the protein I just assume I am getting enough based on what I eat, and if I feel a bit short for the day I will supplement in the evening with a protein drink or something similar.  My surgeon did not put me on a calorie limit, just the amount of protein and carbs I needed each day.  Obviously, I am not able to eat as much when I limit myself to 3 meals and 3 skim milk snacks.  So I have to be protein aware at every meal.  But counting I don't do any more.
