question and tylenol and alcohol

hey guys, so a few days ago i had a gnarly headache at work so i took two extra strength tylenol (1000mg) at around 4 pm and then around 10pm i started drinking and finished around 4am, and drank about 9 beers in that time span. i don’t drink often but i have been taking tylenol almost every other day for the last week and a half, but always 1000mg. woke up with a nasty hangover, and did a little research because i never wake up with hangovers; only to find that tylenol is the worst painkiller to take regardless and especially with alcohol. am i gonna be okay? or should i be worrying that my liver is gonna fail. as far as i know i have a healthy liver but just wanted to see TIA
