Not proud to admit but I average 8 cups of coffee a day, my tolerance is through the roof. I also pound coffee in the morning because I'm so groggy from my night time meds. Can't be good for you! So I'm cutting back to six, then hopefully 4, then 2 strong cups. Weening seems like a good option.
Plus the price of coffee is outrageous, even the cheapo Folgers is $10 for the large.
The average cup of green tea has 35 mg, much lower than the average coffee (100-200mg) and lower than other teas (~50mg). Maybe you are thinking of pure matcha? That can have more in a large potent cup, but the typical serving even of matcha is around 30-50mg.

Thanks for the correction.
