Not sure if you realize this, but you posted this to your personal blog, not as a question to the forum, so you won't get the same exposure. But, to answer your question, you need some perspective.
Pre-sleeve, your stomach could hold, let's say 80 oz fully distended. You just had most of your stomach removed and it now has a capacity of around 6 oz and can't distend. So, before, you would take an 8 oz bottle and chug it down, no problem. 8 oz into an 80 oz container ... you used 10% of the space. Now, fast forward to post-sleeve. 8 oz into a 6 oz container ... hmmm ... it's not going to be the same result.
I'm over 18 months out and no, I cannot guzzle water the way I used to. I can't eat food the way I used to, either. But that is the way I wanted it and needed it. Once you get used to it, it is no big deal. I actually appreciate the fact I can't inhale food and/or drink now. That is part of what got me into trouble.
