Same thing happened to me too! Just be careful!
J Pouch life expectancy is different for everyone. I have met people on here that have had Jpouches for over 40 years and I have met people on here that their Jpouch lasted under a few months. It depends, things can go wrong or right, nobody knows what the future holds, I would just say plan for the worst, always have a back-up plan and enjoy the present
