Stretching of the pouch? (Xpost)

How easy is it to do? And how much food would you have to consume to do it over time? I'm just curious?

According to my surgeon, it is not very easy to do, but over eating continuously over time WILL stretch it out.  Stay within your surgeon's guidelines and you should be well.

I have this same concern only because I drink water pretty fast. I sip it but I drink about 5-7oz within a half hour. I never get the feeling of fullness but i still worry.
