I used to drink gallons of coffee years ago .... I went to Europe on several trips (I'm not a rich man, I'm a budget traveller) ... and I realized that espressos are a far better way to deliver your caffeine hit without all the inconvenience.

I work in a bit of construction and renovation and it was normal to drink about two liters of coffee while I worked ... trouble was, in half an hour, had to go for a pee, then regularly pee every hour after

Now when I drink espresso, I drink one or two, never have to go to pee for hours. I do manage my water intake and drink water if I sweat too much or just get thirsty .... otherwise, caffeine is delivered by espresso ... really convenient especially when roofing, or working in a high place and you don't want to waste time running down at the worst possible moment.

Now that I'm older and middle aged, all those gallons of coffee really don't help me because they'll make me pee every 20 minutes!!! so espressos are far better in my opinion.
