What happens if you quit caffeine for a while? Have you tried to measure your tolerance?

I've found that caffeine tolerance is a huge factor in how it affects me, but tolerance changes quickly. A month off of caffeine for me is a complete reset and a few weeks do a lot to drop my tolerance.

I also have a very high tolerance for caffeine. I took 3 months off caffeine, (I just quit cold turkey) then went right back to it. I didn't notice any changes in tolerance, enjoyment, cravings, or anything else. And for reference I normally drink about 8-10 cups a day.

Sometimes I don't have a coffee for weeks or months because it's good but it doesn't have any effect on me. I never had problems at getting asleep in either case.
