Why did I not get drunk?

Not that I wanted to particularly but I’m alarmed at how I haven’t gotten drunk from drinking so much last night? I was at most tipsy.

I haven’t drank for months so my tolerance should have decreased. I’ve been eating well, exercising, hydrating.

I did eat with my drink but I had

2 beers 1 wine 9 shots

And I was fine? No hangover nothing. I’m quite alarmed tbh, usually I’d be trashed with this much alcohol. I was tipsy but not drunk.

I’m 5’1 and 100 pounds.
