But you never had to quit - studies don't indicate that moderate caffeine consumption had negative health effect, even had unproven heart benefits (as a runner, it certainly doesn't make me slower). And I don't think this is the result of "Big Coffee" skewing the scientific consensus.
I quit (each time) because I didn't like the withdrawal symptoms I was having on the weekends, when I didn't get enough. I went back to it (each time) because everyone else was doing it, and it seemed so easily justifiable.
To each his (or her) own. I'm not an anti-caffeine zealot. If I was, I wouldn't have been married to my wife for over 30 years. I like the way I feel when I'm not on drugs, but I don't disparage those who do them.
