How much coffee is enough coffee?

Up to around 400 milligrams of caffeine is the limit for most adults. That's roughly 4 cups of coffee (however this can vary a lot depending on the kind of coffee && size of serving).

What harm can be done by one cup of coffee early morning?

None. Coffee is actually healthy and has many benefits if you don't overdo it (starting from increasing your energy to making you smarter (improves various areas such as memory, reaction time)).

OP is overreacting and drawing to conclusion based on a small sample of data. I have never felt addicted to coffee and have drank an uneven amount of cups per day throughout my life.
