This is a really tough problem..he is on a huge load of drugs, and certainly too much from my point of view, especially if he is disoriented and disconnected as you describe. Sometimes the patient begs for relief from pain, and more is given..I would work with your husband, and have him ask for a reduction in medication, and also work with the doctor. If no response, you can always change doctors. In any case, chronic pain is a tough issue for everyone.
