It was a poor night of sleep last night, and this morning....on my way to a German language class in town.....I stopped to have a double-espresso.
For those from Bama who've never had an espresso....it's a shot-like container with about 80 to 110 milligrams of caffeine in it, which you balance against a large cup of coffee which would normally have about 120 milligrams of caffeine in it. Some German coffee shops make 'low', and some go to the 110 level.
So I stood there and asked for the double....at a shop which goes for the max level....so I was set to get 220 milligrams of caffeine....in a fairly small cup.
Well....the lady accidentally punched the button twice. So I ended up with a larger sized espresso cup, with four shots of 110 milligrams each.
About 30 minutes into the class, I came to realize how wired up I was and focused to the max. It's not something I would suggest to folks to binge upon.
