My wife and used to be that way, at least on weekends. We'd make a pot and drink it until it was gone. Of course, it would get rather burnt-tasting by the end. Once we started using a Keurig and K-cups, we found we drank less because we only drank a cup if we felt like it. I guess there is a feeling that one may as well keep consuming it if the pot has been made.
As time has gone by, I find I cannot tolerate the bitter taste of coffee as well as I used to. For decades I drank strong, black coffee. Now I have to add cream and I don't tend to drink it past 1:00 PM. Usually 2-3 cups per day is enough for me.
I used to hate the bitterness in coffee too. Those were the days when coffee was perculated. Once the drip coffee makers came to us, I discovered I liked coffee, it wasn’t bitter. You can make it by the cup or by the pot, and as strong as your heart’s desire.
However, burned coffee is horrid. So, I shut my pot off so that the burner can’t keep cooking the coffee. As a result, each cup tastes as good as that first cup. In the winter, I can reheat the cup in the microwave as long as its not over heated. In summer, I pour it over ice cubes with sweetner and cream and have a refreshing iced coffee. Ummm, delicious!
I do have to watch that evening coffee because then it can give me intense heartburn.
