If it were me, I'd ask my doctor about going to 200mg of Celebrex and get off the norco. A lot depends upon your age and heart risks. They don't really know what the effect is. Everything is a trade off, of course. But no one should have to live in constant pain. I couldn't stand the narcotic painkiller because it made me horribly constipated.
Good for you losing 120 lbs!
Best of luck,
