Turns out that daily use of a drug leads to negative effects that take a long time to reverse.
Consider that all of these are symptoms of caffeine withdrawal.
I hope you're comparing to how you were before ever drinking coffee, rather than how you were feeling in between periods of use. I can hyperbolically guarantee that a person who has not ever used caffeine will think better, be more productive and more organized than a person of similar health who indulges in caffeine daily. On /r/decaf very few people will ever want to go back to coffee once they've gone 6-12 months without it.
Mmm no, I remember exactly how slow I was before ever drinking coffee.
I even quit for 5 years, and got back on 6 months ago.
I hated myself without coffee, I'm great with coffee.
