I found my husband's hidden stash of sex toys (in the trunk of his car) and there was a vial of something called "Jungle Juice" in there.  I asked a gay friend about it, and it sounds like some version of what you're describing (I looked at the link you posted).  In 2016 (before I knew what was going on), my husband started passing blood in his urine, and his doctor took him off all medications that could cause liver damage, and he had to stop drinking (briefly).  They monitored his liver for a while, and after a while decided that he didn't have "permanent" liver damage.  So now he's back on whatever meds he was taking, and drinking his usual excessive amount.  When I found the "Jungle Juice" I did wonder whether something in that had caused the liver damage.

That was then, of course and this is now.  Now if he gets liver damage, as far as I'm concerned he worked long and hard to earn it.
