A Stoic would likely drink her coffee quite strong with very little milk (if any). There would be absolutely no sugar. She would drink her coffee strong so she would have just enough anxiety to test herself against her anxious proto-passions. She would have very little milk as not to dilute the bitterness of her coffee. The bitterness reminds her of the adversity she must overcome in life. The high caffeine content will increase her alertness and focus and allow her to use her hegemonikon more acutely when making her daily decisions. That’s how a Stoic would drink her coffee and she might have three or even four servings of it, depending on how strong.
