If I understand you correctly, our circumstances seem inverse. I drink rarely, less and less as time goes on. I drank sporadically, mostly socially, in my 20s. I have 35 years now.
And maybe it's just cheap beer? I used to mostly drink gin but I haven't had much occasion or enthusiasm to do so.
My big poison is sugar.

I found this started to happen to me by late 20s. Being Scottish has a lot of cultural norms around alcohol consumption (mostly excessive). I suffered with horrendous full day hangovers.

I’m now 2.5 years with no alcohol and it’s one of the best decisions I’ve ever made.

(Not intending to preach the sober life, but I sympathise with the feeling of a developed intolerance)

Woke up with a headache today. I think my body may have developed an intolerance to alcohol. It seems every time I have even a beer, my brain goes to mush the next morning.

Other than that, I'm looking forward to this week. Relaxing a bit today, prepping for my podcast, and then bitcoin brunch tomorrow!
