A lot of doctors are not informed about codeine addiction. Before seeing my current one, I saw a different one who just shrugged. I am on 2 x 30mg per day and I also suffer with endless constipation, so I know where you are. I tried to reduce to 1.5, but after 4 days I couldn’t go on, explosive diarrhoea. I put off owning up to the doctor, but I really think you have to, and I hope yours is helpful. Stay in touch. Roger
