It will differ for each person...there is no way to tell how you will respond as an individual.
That said...I can speak to my experience....
The only time when I experienced anything other than mild discomfort was bedtime the first night after surgery...it was a little hard to get comfortable. Had a pain shot and was out like a light.
I was pretty unstoppable. Woke up from surgery and wanted to start walking. Got myself out of bed with no problems...surprised the nurses, and just kept going. Day after surgery, I felt very much like myself, and went home that night.
Incision pain was pinchy for about 3-4 days. I'm two weeks out and could easily do crunches or a rowing machine, but I'm being good and just walking 7 miles a day instead.
The only thing that really slowed me down was a lack of calories. Needed fuel to think, heal, move. Once I got eating a little more, I felt terrific.
