What is moderate drinking for you?

Without turning this into a word salad I’ll try to get my point across. I’m a 27m who has started cutting back on my drinking, primarily to shed a few pounds and not feel so bloated, but also another reason I’ll go into further below. On average I’ll have maybe 10-15 drinks a week at very most but normally those during Thurs-Saturday. Those nights I’ll usually have anywhere from 4-7 over the course of an evening, maybe between 5oclock and midnight. Sometimes I’ve gone overboard and closer to 10 which yes I know this is bad. There have been other times where I’ve extended my drinking into the week and for a while during a rough patch I was drinking 6 days a week maybe 4 drinks or more every night. Eventually I would slip up at home and get sloshed and twice have called out of work due to hangovers. These were spaced out by months and I felt terrible for doing so and limited my drinking for a time after these, but it still worried me.

Second big reason was I was in the liquor store last week and a woman ahead of me in line was telling us all how she had completed a small rehab course and was 40 days sober and getting a few (at least 4) of those small bottles they always keep by the registers that are like 2-3 shots a piece. She said she used to drink 750ml of tequila a day easily and would often wake up in the night needing a drink. You could just tell she was gonna relapse hard. This unnerved everyone you could tell and one lady asked her to call her sponsor and politely guide her. I felt bad for the lady and honestly it scared the shit out of me for a moment. I was terrified to think what if I was like that one day. I haven’t had a sip in over a week to no negative effects or cravings. Like I said I think I moderate it well but wanted others opinions.

On one hand I get being young and if you generally have no negative effects and causing no harm then it’s cool but also the overthinking and worrisome part of me that says go cold turkey so you won’t even have the fear of being like this lady. I really just have a few drinks at the house to help relax and play some games or watch shows in my off time, I don’t drive out in public or go to bars ever. How do you define moderation and does anyone else wonder about this?

TLDR: what does moderate drinking look like for you? Do you ever think you might need to cut back? Why or why not?
