Hi Fazer,
Try not to worry too much about your liver. I use to take lots of paracetamol with my codeine and my liver tests were always normal. I’m sure yours will be fine. And stay away from Dr google, I learned the hard way that it’s not your friend ????
I understand what you say about your doctor, I couldn’t get an appointment with my usual doctor so saw a different one, and she was rubbish, I was crying, riddled with anxiety and she told me to just not take any more codeine but I’m not withdrawing it’s just anxiety causing it all!
Thankfully I managed to get an appointment with my usual doctor a couple days later and she was amazing as always. I broke down and she explained to me, told me it takes time to settle and gave me some diazepam.
Like Warby said CT is horrid but quicker, if you decide to taper I think there are some links further up on this thread about how to do it.
Good luck either way ????
