Giving up one of my meds. Cocodamol 35/500 (Sideeffectwhu)

I am still taking Pregabalin 200mg, butrans patch 10mcg and Amitriptylene 25mg. But i want to give this one a go as a start. I asked for this two years ago and was told to take it when required but I knew I was going to take it as a feel good thing to get..
