You are weak. You merely adopted black coffee. I was born into it, raised by it. I did not taste light roast until I was already a man, at which point adding sugar did naught but ruin it.
I used to drink two pots of death wish every day, along with a potent cocktail of antipsychotics, antidepressants and anxiolytics. I went cold turkey just for laughs. They said I might die. I did not, but fucking hell was that a hard 6 months. I feel much better now, but my cajun-grade caffeine tolerance remains. Even my grandma drinks a pot or more a day. It is rare that any Cajun grandmother be without a cup of black coffee in their hands at any hour of the day. A lot of cultures have taboos about drinking coffee at night. South Louisiana almost considers it taboo to not drink coffee. I swear my entire ethnicity has drank so much coffee over the past 200 years that we’ve developed a collective immunity to it. Well, that, and we cut our beans with chicory root so it’s more darker and makes you go zoom less.
