I don't really drink a lot of beer, but when I do, it's usually thick stouts. I don't drink much alcohol at all anymore. The days when I did, it was more or less a contest or a dare among friends, when out and about.
I drink absurd amounts of coffee. Coffee has some anticeptic aspects, but what role that plays in its interaction with my gut flora is anybody's guess. I have to figure my microbiome has evolved adaptations to cope. Or not. Maybe it's just constant churn, who knows?
I fart constantly. I'm not shy about it. I let silent ones rip all the time. Most of the time, it's odorless air. But when it's not, I crop dust my co-workers shamelessly. They can deal with it. Smell my innards. Inhale the fumes of an ecological menagerie roiling inside me. Gas isn't really an unhealthy thing. It's just a perception of rudeness, like body odor, nose picking and so on.
...oh yeah, I pick my nose too. Like a fiend. Is that considered "bad" or something? Whatever. I look at is as another form of seeding the microbiome, applying the latest patches and AV updates, to harden my system against intrusion.
My shits are huge. They are solid and a brown, like some hue Bob Ross would concoct for the trunks of his trees. When I'm sick, it creeps into an acidic yellow, like vomit, but with an acrid stench.
As for mental fogginess, I can't complain. Maybe the coffee sobers me up.
Reading between the lines, with the gas and the bloating and the fogginess, I'd guess this resembles a drunkenness that draws parallels with anaerobic production of alcohol. Take it too far, and you might be brewing a lightly alcoholic mix, not unlike how kombucha requires ID, even though it's hardly comparable to beer.
