Every doctor gives out different information. It's a bit frustrating. You will be able to drink more than just a sip of water at a time down the road, you really should be trying to get to 128 oz of water a day, as per current medical research. You'll be able to down all your pills at once with water at some point (more than likely). Pretty much post op you'll want to keep things small and limited to prevent issues with healing, once healed you are working to try to limit how much you stretch your pouch, I say limit and not prevent, because never stretching the pouch/sleeve is almost impossible. Once you are healed, you'll find that a LOT of what they told you that you'd never be able to do... you can. This is where the will power is going to step in over all the restriction you had while healing. Things will start to feel "normal" and you'll be able to eat more and certainly drink a lot more. So, up front, follow your doctors orders, just understand that, down the road you'll be able to change things up, you *will not* be sipping slowly for the rest of your life. That's pretty much a given.
