I was back at work in 5 weeks. It was a full belly cut and repair on the bladder. I seemed to get more and more strength as the months went on though. My suggestion for you is take as much time off as possible and then slowly add hours if you have the luxury. Don't overdo it or it will take longer to make a full recovery.
