Something I've always noticed and am going through now. Sometimes I'll drink too much the night before and be concerned about a hangover the next morning. Morning comes, and almost always my first thought is "gee I feel like shit but actually this is way less bad then I was expecting" this misplaced optimism gets washed away at an indeterminate length of time later when a wave of awful nausea crescendos to a peak of crappiness before gradually receding leading me to think "maybe that was the worst of it" only for the cycle to repeat.
This happens even when the hangover is not one severe enough to have caused vomiting. Feeling sick from drinking too much I understand, but I wonder what's physically happening during the peak of these waves that's not happening during the troughs.
While it's cool to show concern for someone who might need to hear some words of encouragement for getting help (well, minus the scare tactics of a dead relative story), you seem to have conflated this poster's description of the 'pattern' a night out drinking can take with a 'pattern' of problem drinking every day, or far too often at least.
What they described is perfectly familiar to me, someone who drank to a level of bad hangover on occasion when I was young and having dumb fun with friends. As I got older, that type of fun got less important and the amount I drink came down to a drink or two, rarely, when I can afford a nice whisky or something.
Basically, someone recognising how a night of social drinking can turn into a hangover isn't necessarily the cry for help you seem to have read it as
