When was your surgery?
If it was recent, I think you should sip.
I've found, though, as time goes on you can drink a little faster. But your tummy will tell you if it's too fast.
I think it varies with the amount of swelling you have. I was able to drink 8oz in about 30 min after the surgery as long as i sipped on it. 4 months later I can drink a 20 oz in about 15 min. I notice this seems to really vary though with other vsg patients and ymmv.
