I know exactly how you feel! I have quit coffee but I always go back to it. When I was off coffee last time, I was hiking the Pacific Crest Trail. I noticed I always felt really great the day I left a resupply town. Invariably I had a big breakfast in a little diner before I hit the trail again. I totally attributed it to the pancake sandwiches I would usually order. Then one day I acquired some chocolate covered espresso beans and got the same revved up, I feel Great, I'm Super Woman!!! feeling. I realized it wasn't the big breakfasts, it was the coffee. After that, I realized quitting coffee is both good and bad. Good because when you have some caffeine it really works on you and feels incredible. Bad because then you don't get that good feeling every day.
I want to quit coffee, but I also don't want to quit coffee
