I was in a lot of pain after surgery, but I think that was more mental than physical, but I had a morphine button, too. I was up walking within 3 hours - it really does help the gas pains!
I was also sent home with percocet, which I have used after I've done my daily walking. I have tylenol, too, which got me through the first night at home.
It is very individual, but just know it's totally worth the temporary pain.
