I've begged for coffee as kid. Dad, would let me, but no sugar no cream, we were just to poor for that. Mom would make coffee gravy and biscuits, if some left over coffee was in the pot, as she made the first pot of that day.
Now, 60 years later, we use a Keurig maker.
After waking, while reading, I'll drink 3 maybe 4 cups. A morning blend, then a donut shop, then a extra dark, then whatever grabs my attention on the coffee carrousel, that holds the pucks.
I do not like to eat anything before 12:30 to 1:00 pm or so.
After I eat, I hammer water, till around 5:30 - 6:00 then have another one or 2.
By 7:30 I start nodding out a bit, to TV psychoses drivel, and copious amount of ganja.
Coffee, never keeps me awake. Well the stuff we drink anyway.
