Op here. I don't have sugar in my house, haven't had it for years. It's not needed for recipes I use, it's not in bread I bake, I would have no use for sugar.
But sugar is IMHO not mind altering drug like caffeine, sugar is just pure calories.
Nobody does that (or almost nobody?). Sugar consumption comes from almost everything nowadays, from white bread to sauces to... everything. Or maybe your comment was ironic and I didn't get it, sorry then.
I didn't go for ironic, but it was meant rhetorically. Attacking the OP by equating coffee intake with sugar intake is a bad faith argument, precisely because sugar is a prevalent food additive while coffee is not. Moreover, the OP clearly said "drinking coffee". not "ingesting coffee/caffeine".
