Daily drinking (20 year old)

I am 20 years old and have been having around 6-10 drinks a night of heavy beer (Guinness – stout – larger) for the past year and a half to 2 years. I quit weed about 2 years ago after being a heavy stoner and tried some other alternatives like kratom which isn’t scratch the same itch, I have had substance abuse issues since I was 13 but that’s isn’t very relevant to what I’m asking. This post isn’t asking for help with quoting just genuinely curious what the long term effects look like from someone who has been in a similar situation. I work 65 hour weeks and don’t let it affect my work or anything in my personal life but before bed it routine that I drink, I am not planning on quitting in the near future but am asking that people reach out with there similar experiences.
