If so did it repair itself also, what takes more of a toll on your liver gear or alcohol?
Gear is harder on your liver than alcohol.
People who develop liver problems over alcohol are usually also taking advil to cure their hangovers, doubling the toxicity. Usually heavy drinkers, especially women, are on medications to which also add to the stress on the liver. And liquor is also harder than beer on the liver.
People drink beer for years and years without liver problems. On the other hand Ive known 45 year old women in complete liver failure over their drinking problem, gin or vodka in the day time, wine in the evenings, day drinking, hiding it from others etc...
Gear is harder, depending on the gear. I think if your responsible you can probably have a few beers during a mild cycle. But when it's a harsh compound and you're partying pretty hard, drinking hard liquor and having multiple drinks multiple times a week, you're going to impair your liver.
How much? It varies from person to person. Do you have elevated liver enzymes? If you catch it early you can stop whatever is causing the damage and in time it will repair itself. If you're pissing ffrothy bloody or brown urine. Youre probably going to have pretty severe problems, maybe even long term. If your skin and eyes are jaundiced? You're probably fucked.
