You need to knock the paracetamol on the head, obviously. I'm not being callous. That is the single issue, ale has nothing to do with anything here, of course medication can **** your liver.
I had a liver injury (unknown origin, suspected vaccine injury, actually) and it took the better part of 2 years to get my ALT back to normal.
The good news is that if you pack it in, the liver can regenerate, and with that comes better ALT results etc. Hopefully you've not done so much damage that this can be a prospect for you. Your doctors should be able to better advise.
