I have two big strong double espressos made from my home machine first thing in the morning, then no more for the rest of the day. It takes me a very long time to become alert after waking, and the coffee is an important part of that. I've been getting up at 5:30am occasionally to ride before the heat. It takes me those two coffees and until at least 6:30am to feel alert enough to head out. I cannot wait for cooler weather, because this sucks.
