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.
I'm actually trying to do the same. I've been getting nauseating headaches for the last couple of months and finally narrowed it down to my caffeine intake. Not really proud about it but I was probably at about 1,000 mg a day easily. a pot of coffee, a soda or tea, and usually an energy drink each day.
Right now I am trying to get off of energy drinks full stop and limiting myself to 2-3 cups of coffee in the am.
I have however fallen completely off the alcohol wagon. I am not sure if I am gonna try to get back on or try really hard to limit my beer and wine to 1-2 every so often.
