There is no fluid limit in your 21 day post op time frame. Most people end up not drinking enough and get dehydrated. This is not a calorie counting time either. You need as much fluid as you can get and your diet above doesn't seem like you are getting enough fluid at all. You should basically be sipping throughout most of the day.
When I was first banded, I was vomitting a lot and it was from being dehydrated and not drinking enough. See, contrary to popular opinion, the majority of a normal persons water intake comes from food. In fact, about 80% of your water comes that way. So since you are not eating food you can see how you would need to up your fluid intake to make up for missing all the fluid in your foods.
Dr. Ortiz, Dr. Romero and Dr. Martinez all told me the same thing, you need to be slowly sipping some sort of fluid throughout the entire day. They told me that 3 bottles of gatorade and 3 bottles of diluted applejuice and another 3 cups of broth and then several bottles of water were a good gesstimate of how much is needed during the first 21 days. Now, I am not positive whether or not, that was an individual thing or meant as a bases for everyone, but I do know that there is no limit on fluids during the 21 day time period.
