Ok thanks.
I was in a very similar boat with pure codiene and then morphine. It went on for a very long time.
There are two options here. Ideally speak to the go and see what support they can offer in terms of a taper plan, by tapering that is a gradual reduction over time so you can come off them.
Otherwise it’s tapering down yourself slowly over time.
You have to be very careful or you could slip into withdrawal cold turkey and that’s not a nice place for anyone believe Me. I went through it
