I'm a few days a head of you. They also repair a hernia on me as well during surgery. My stomach did not really hurt after surgery, what was the worse was my shoulders and all the air that was pumped into me for surgery. I am now on the modified liquids and everything everything seems to be going down with no problems. I will admit though I am still taking 1/2 dose of pain meds since I tend to sleep on my stomach.
Good luck! Lets stay in touch.
