So I’ve historically been told I can get too drunk.. I took a 3 year sabbatical and things have been fine. However; now when I do choose to drink – it takes me a lot to get “drunk” I don’t mean drunk like passing out or pissing myself, I mean drunk where I feel fun and just loosey-goosey. Like it takes way more alcohol than my friends drink to get on their level, and I feel weird about it.. It’s not that I get shit faced, but like just to get on the same level as my friends it’s like I’d have to drink twice or three times as much as them. There’s no issue with me driving or anything when I drink – the only thing is that it literally takes me significantly more just to get on the same level. I want to reiterate the issue here isn’t me becoming sloppy or anything like that – it is literally that when we buy I bottle I drink more than everyone else but am noticeably less intoxicated – to the point where people say things. What can cause this? I wasn’t even a crazy drinker before, just got a DUI and stopped for a while… can anyone relate? I really don’t need negativity about this because it really isn’t a problem, other than if I want to drink like my peers I have to bring my own

edit: by no issue with me driving it means that I would not drive / that is not applicable – not that I feel i’d be able to drive after any amount of alcohol
