I've been banede for a couple years and during this time have had a tummy tuck and several ortho and overuse injuries including a rotator cuff and a ruptured achilles tendon. I've taken Advil at will and post-surgical percoset with no consequence. My band doctor is one of the best in the country and is far more laissez faire than most. Of course you should go with your doctor's orders, but I'm an Advil girl and it hasn't been a problem. I don't even think about it.
