My husband usually brings me a cup when he wakes me up - I’ll drink maybe half of it (if it’s fresh - if it’s reheated/burnt smelling forget it). That’s usually it - once in a great while I’ll have a small cup at work, but that’s a rarity. I usually drink iced tea all day long (well at work anyway - two 16 oz bottles.)
I keep it down to a pot and a half a day. My wife has 1 or 2 cups. When the coffee maker broke ,she suffered withdrawal with severe headaches and upset stomach.I had none.
