Nothing wrong with feeling good. I like it. It's just that if you quit coffee but have it infrequently, when you do have it, it really revs you up and makes you feel amazing. If you have it every day, you don't feel it quite so much. You get used to it. If you quit entirely, then you never get to have that feeling. The trick is to quit but not quit. I haven't figured out how to do that.
