Jacker as usual has dispensed some awesome advice!Heres a thought-if real soon you cannot commit to complete sobriety you may very well find yourself going on a permanent vacation for the liver is ASKING you to stop feeding it alcohol!
Based on my experience, you should stop drinking 100%; at least until your numbers go back in the normal range. But if you've been drinking a bottle at night for the last 25 years, you should seriously consider a complete change in your lifestyle, if you want to remain healthy. I did the same kind of drinking and I am about your age, but we all get older and that kind of lifestyle cannot go on forever without serious consequences. A CT scan or ultrasound would tell you more about the condition of your liver. I had one, and in my case it showed fatty infiltration of the liver, which would be common for a heavy drinker. That is generally a precursor to cirrhosis if you continue Drinking. The good news, is that your liver has incredible regenerative properties if you clean up your lifestyle. If you really think about it, those two glasses of wine on a Friday night will probably make you want more. Our bodies adjust to the amount that we are used to drinking, or at least that is my experience. So part of turning over a new leaf, involves new coping methods........ Something other than alcohol or other chemical abuse. If you stay clean and sober for 90 days, I wouldn't be surprised to see those numbers improve. But if they do, don't take it as a license to drink the way you used to drink. I hope that all goes well for you.
