Drinking decaf ~one week a month is a good way to reset your tolerance
If you'd drink one week a month decaf (assuming you can enjoy the taste. I dislike it) you get caffeine withdrawal the first day, and the other days you don't. But as soon as you start consuming coffee again, you also get withdrawal symptoms because the half time is ~4 hours.
The way I deal with it which is the correct way is limit coffee intake to 2-3 cups a day in the morning/afternoon. None in the evening because it will cause sleep deprivation.
