How many Percocet's do you take/are prescribed? I ask because percs have acetaminophen in them, and it takes as little as 4+ grams of acetaminophen to cause permanent liver failure, while many OTC products have as much as 500 mg of acetaminophen in them, and perc concentrations can range from 5mg oxy/325 acetaminophen to 30+ mg oxy/500 acetaminophen, etc, it can be easier to OD not on opiates but acetaminophen depending on the ratios and how many you take. Check your intake, it is an underrated cause of liver damage as a lot of people take 10+ Tylenol, etc. and one-shot their liver, and prescription errors are shockingly common. Tylenol/acetaminophen literally kills 1000 + people a year and causes 50,000 + permanent liver damage cases. In any case talk to a doctor, and I would suggest N-Acetyl-Cysteine/NAC, as you can get that at Walmart or any supplement store and it is an amino acid directly used by the liver and can directly rebuild the liver even in severe cases. I know someone who lost 50+ percent of liver function from attempting suicide with vodka and a whole bottle of Tylenol pills (most were puked up to be fair) and she is back to 80+ percent with NAC and clean living for about 6 months.
