I have difficulty sleeping if I have coffee too late in the day. So, my favorite time for coffee is just after I've woken up with breakfast. Nothing like having some freshly brewed French Press along with a couple eggs over easy or an egg on an english muffin with cheese or some yogurt with fresh blueberries or oatmeal with fresh blueberries. Two mugs to start the day is all I need.
fr bro. like just anytime I wake up whether it's in the morning or afternoon. I believe most people like their coffee in the morning too. and coffee reduces the ability to fall asleep I guess so you wouldn't want to take it in the night
