My first all night coffee binges started in 1990 while working nuke security in upstate NY as an MP. Our coffee came in a white can with black letters, "COFFEE GROUNDS". That shit killed my tatse buds and now as long as it has caffeine it'll work.
Recently when I go into the local Starbucks right before they close and the Pike is out I get an Americano. I will probably try an espresso from there in the near future. After 2230 i hit the Sheetz as their coffee is ok.
At home I do the Keurig thing....its just easier since Im generally the only person drinking coffee in the mornings.
