Minor what?
And yeah, two things:
1) It's telling that -despite the fact that the closest store that I get my coffee and tea from also sells cigarettes (and that I'm so obviously old that they don't ask me for ID, so that minor inconvenience isn't a factor)- I've been able to quit nicotine, but never able to quit caffeine.
2) I can't even count the number of times I've consumed a mug of tea or coffee for no other reason than to avoid withdrawal symptoms. Cigarettes were never like that for me. Just like caffeine, I inevitably developed a tolerance... but working through nicotine withdrawal was annoying, rather than _painful_.
