>But among the available addictions it’s one of the best.

Why do you feel that way? I've never been a big coffee drinker (for this reason specifically), but everything I've heard about caffeine withdrawals for people who have been daily drinkers for a while is that they are awful - headaches, irritability, extreme fatigue, etc...

The withdrawals are unpleasant but certainly manageable. A good week and you're effectively detoxxed, two and your brain is reset. Moreover, as long as you refrain from adding sugar/sweetener to your coffee it's closer to a benign habit than an addiction, as black coffee has little to no downsides if your heart is ok.

This is coming from a pot/day drinker who's 'quit' multiple times. In the end it's not worth it, because coffee also comes with the pleasant social contract with other coffee drinkers as well as a appetite suppressing effect.

Coffee helps me with fasting. It turns what is a semi uncomfortable experience to an easy thing.

People have told me that, for them, if they don't get their morning coffee that get symptoms like headaches. For me, it's mostly just a habit to have tea or coffee in the morning and relax before starting real work. I like it, but if I'm traveling and there's a line out the door at Starbucks or Dunkin' Donuts, I'll probably just walk on past. I don't really care that much.
