My husband has been taking Norco for the past few years for knee pain. He is prescribed 120 tablets per month. He always runs out prior to the months end, in fact most of the time within the first two weeks. I have counted him taking up to 10 a day. Recently, he was also prescribed 100 tablets of Tramadol, at the same time as the Norco for the same month. I am wondering how the Dr. can justify this type of treatment. He goes to work but he is withdrawn at home and sleeps alot. I have left him once due to this situation but when I confront him, he gets very angry. Is he just plain addicted or is he trying to kill himself, I am beginning to wonder. Is this normal?
