Question about drinking before/during meals

I had these checklists and guidelines for my pre-op life.  I ignored some of them, like the low-fat one since I think fat is an important part of a healthy diet, but it seemed like a good starting point.  

Eat 3 meals a day, but no snacks.
Always stop eating or drinking as soon as you feel full.
Eat slowly! You should take at least 20-30 minutes to finish each meal.
Do not drink with your meals. (30 minute rule)
Do not drink liquids that have calories (1/2 cup fruit juice a day is ok.)
Always eat protein first.
Take your multivitamin supplements each day.
Exercise regularly, 30 minutes a day. (I’ll need to walk only for the first 6 weeks after surgery.)

The checklist is as follows:
I eat three times a day (breakfast can be a protein shake)
I eat at about the same time each day
I have decreased my portion sizes
I eat at least 3 servings of vegetables a day (1 serving = 1/2c)
I eat at least 2 servings of fruit each day
I have cut in half the amount of fat that I add to foods
I am choosing low-fat products more often than I choose high-fat products
I only eat sweets, desserts, and/or candy one time per week
I only eat fried foods one time per month
I have increased my activity
I have cut in half the number of caffeine drinks I have each day
I have cut in half the number of carbonated drinks I have each day
I drink at least 64oz. of water each day
I sip all my drinks slowly
I take a multivitamin each day
I have practiced chewing my foods 30 times before swallowing
I have practiced not drinking during or 60 minutes after a meal
I have a set of measuring cups/spoons to use for measuring after surgery
I have tasted and purchased a supply of the supplements I will use to get most of my protein after the surgery.  

Use the search and read up on your pyloric value ... frisco has done it many a time !!! It's very interesting why and how we should do it !!! I will drink right up till I eat .. how ever I won't drink for at least 45 mins after  .. The longer the better !!! :-)
