One way to avoid the headaches is to taper slowly off of caffeine over a few days instead of dropping it completely. Just lower the "dose" you intake each day

Yes I try not to drink coffee for more than 7 days in a row. If I do I know I have a "detox" day ahead of me. Which is basically me not drinking coffee on a Sunday and suffering through a big old headache, sleepiness and possibly a little bit of nausea and dizziness. The coffee ween off is real.

I had heard it was a bad headache, so I also tried weening myself off it with ever smaller scoops of grounds. Still, when I finally quit, it was a much stronger headache than I was anticipating. It really was one of the worst headaches I've had, and it lasted ~two days.

That said, my SO will never let me have caffeine again. My SO says that I am so much nicer to be around and that I sleep much better too.

I don't anticipate going back on the java, my life is much better. But everyone is different!
