Coffee does not keep me awake, it never has. I drink coffee because I enjoy the taste and it's comforting on cold mornings as well as evenings, or any other time. I don't understand the problem.

jfhubel, and diet drinks are not good for you either. Love coffee, but not a pot a day.

Ever since my service days I love my coffee and will often drink a pot a day or more with no ill effect. My wife drinks almost nothing but diet Coke :( How a person can drink soda with a piece of pie, a donut or a nice piece of cheesecake when there is a good cup of coffee available to me is abhorrent. I have to look away :)

I enjoy at least 3 cups a day. Even if I have a cup before bed, it doesn’t keep me awake.

Coffee never kept me awake when I was younger. But the last 10-15 years, caffeine can keep me awake the entire night if I drink coffee after 12 noon. I learned that the hard way.

I love coffee and will drink good coffee anywhere any time. But if it is not available I will just as gladly drink wine, beer or any other fruity drink but NEVER tea.

Good video: odd comment on screen about 'whole grain' coffee. You grind beans to make coffee. Are grains something to do with instant coffee? Seems unlikely. Puzzled 🤔
