Oh yes, I do remember now. Not gonna lie, it is unusual to be put on bupe for a codeine addiction. I've never heard of it being done but am not gonna argue with what your doctor has prescribed. If it's working for you it's working. There are other things to be taken into account than simply what you were taking at the time of seeking treatment. I've said before that I was put on bupe again fairly recently essentially to replace codeine. My situation is rather different to yours but it's the bigger picture that has to be taken into account when weighing up treatment options.
