I have been addicted to Codine Many times over the last 20 years  Lots of broken bones and bad back.  Every time I get addicted after long periods of use.    I have found a system that works for me and I am taking 60 mg of Codine a dose every 6 hours.  I decide that I am going to go to every 10 hours for a few days.  Then go to 14 hours, then every 18 hours, then 24 hours etc.  I keep a journal  Whne I get down to gong 48 hours between pills then I am ready to stop completely.  I take some advil for a few days and I am usually good to go.  Hope this helps someones.  Good Luck..
