I had two and suffered no ill effects from the surgery. It is important to rehabilitate the stomach muscles when the doctor gives you the okay.
I also found the the more I moved, the better I felt. As soon as they let me up, I started walking the halls of the hospital and recovered very quickly.
Another tip is the use a "cough pillow." It can be just a small blanket or towel folded in quarters. If you have to cough, press the cough pillow tightly against the incision to support it and it really helps to keep it from hurting.
