Same here, except for me it was about age 37 or so my body decided it was going to react much differently after I drank. Messed up painful guts, wake up at 4-5 am after going to bed at midnight, 3-4 shits the next day, anxiety out of nowhere. If I have more than 2-3 beers on a weekend night my body will definitely not like me anymore.

It’s honestly been quite helpful having my body tell me what to do instead of it just dealing with it.
