The legendary days of the golden age of body building and powerlifting they use to drink like fish. I wouldn't recommend this, but I personally drink one night (light) and additional night may be a bit heavier while on. You'll be fine, just don't push it too hard. A bottle of wine or a few glasses of cognac/armanac will not kill you or your liver. BE SURE to stop when you know you should, that is the difficult part because you'll feel AMAZING when drunk while on cycle. The sex really is amazing as well; therefore, BE CAREFUL and know when you should stop. Once you stop, start guzzling water. Prickly pear extract is the most amazing thing you can experience, but it normally comes in drinks with shit tons of sugar; but it will guarantee no hang over and no dehydration because it super hydrates the liver.
You should be taking TUDCA and I'd take a third dose while drinking. The next day be sure to start off the day with some form of detox. Drinking 1/4-1/2 a gallon of alkaline water and use a liver cleansing herbal tincture to get those toxins out!
You'll be ok, but limit yourself and be intelligent. It's one thing to have a glass of armanac after dinner on a Friday night than to start opening a few bottles of wine.
*Don't be one of those cliche squares who is so obsessed with their body they refuse to go out and have some fun! No one will put up with that, especially a member of the opposite sex. Just have a glass or two and just chiiiiiiiill
