What is your caffeine fix for those long work nights?

During those long work nights, my caffeine fix is usually a strong cup of black coffee made from freshly ground Arabica beans, accompanied by a touch of sugar and served in my favorite mug, as it provides the perfect balance of flavor and stimulation to keep me focused and energized.

I only drink coffee in the morning and I don't advise drinking too much coffee can be harmful to health. And working at night is also not desirable.

my curiosity !
