I used to drink 3-5 cups of coffee a day, starting the day off with a strong cup of French Press coffee. However, I also used to get stomach aches from the coffee and horrible sleep. I decided to make the switch from coffee to tea and have been much happier with my quality of sleep. Also, the stomach problems have gone away. I do, however, long for coffee. But, I know once I have one cup, I'll start drinking a whole lot of it again. So, I treat myself to good teas from mail-order sources so I don't get tempted with coffee. Also, when I quit coffee I had a headache for about two weeks. And, was all around cranky for about a month.
