I am 7 days post op and I drink about 70-90 oz's of water everyday. I DONT CHUG IT but I do drink that much. I drink water, power aide zero, vitamin water zero, and about and other sugar free drink except pop. Anyway, no problems so far.
I have Aetna. i have a surgery date of 4/4/13. I was required to have 4 visits with nutritionist, physiological evaluation and then just normal test and procedures. All in all it was pretty smooth so far.
