Soberwithin: GO TO THE DOCTOR AND GET TESTED. First of all, there is a great chance that your liver is FINE. I say that because I've been a big boozer for 30 years and am always SHOCKED when the tests come back normal. In addition, Naltrexone is a harmless drug unless you have a damaged liver, and if so, it can make it worse! Ignoring medical issues is like ignoring your car when it makes a funny noise: if you get it checked out immediately, the fix is often easy; conversely, if you wait too long, a manageable problem can get A LOT WORSE. You have nothing to lose by going to get checked out and everything to gain with a nice, clean liver test. That will be the best "medicine" for your anxiety and if there are problems, you need to address them fully-informed and not from ignorance. The truth and not denial will help your nerves. I wish you the best. Nick
