Let's separate two things which I think may be different here.
Firstly, there is the matter of the consumption of coffee, and secondly, there is the issue of 'feeling great in the morning'.
Long before I swooned on catching the scent of 'real' coffee as a small child (and yes, even as a small child, if I could persuade adult to give me coffee I did; I never liked soft drinks, but I have always loved coffee), I loathed mornings. Especially dark, dull, overcast, wet, miserable winter mornings.
So, even as a small child, I was not a morning person. I am, by temperament, disposition and character, a night owl. Without my morning coffee, of course I can function. It is just that I don't function as well. So, I prefer to have a mug - or two - of rich, serious, 'real' coffee, first thing in the morning.
So, mornings, I am not at my best. Yes, I can do them, but I am not performing optimally. However, put me at a midnight crisis meeting and I'll ace you. Ask me to research through the night, and I am peerless.
In any case, my first cup of coffee in the day is an experience of pure, unallayed joy, sheer sensual pleasure.
You strike me as someone who is a morning person, - anyone who 'wakes full of energy at 6:20 ready to rock and roll' - is a morning person. Actually, the kind of person I want to assassinate, if they try to waken me up, unexpectedly. In my experience, they don't even need coffee.
