Not sure if you are pre- or post-op, or the context of this question, but for me, drinking fluids is completely different now from before surgery, and I'm over 6 months out.
In the first couple of months, there is no way I could get in 8 oz of water in 2 or 3 sips. I couldn't drink plain water at all without it making me feel sick, and even with flavoring in it I had to take it slow. Now I can go through a 20 oz bottle of plain water in about an hour with no problems and without rushing it, but for me fluids still go down quicker with a little flavor in them. Now that I can drink almost normally again, I have to remind myself to get my fluids in... because if I don't, I can easily forget to drink and end up dehydrated.
