I used to drink a few cups of coffee a day. I've been completely off caffeine for several years now. It's at a point where a single chocolate chip cookie will have me wired for an hour. I occasionally fantasize about the effects that a cup of full strength coffee would provide. This drug is very powerful when used sparingly. It's easy to forget what it used to be like when you're drinking 2+ cups every day for years on end.
I used to drink what was probably an unhealthy amount of caffeine on a daily basis. Not out of any discernible addiction, more as a thing to do that mildly improved my focus and tasted good. I got cut off for the day by the coffee bar at work one time after having an iced latte with 10 shots of espresso, which itself was after a few other drinks IIRC.
It's probably been a decade or so at this point since I've consumed caffeine with any regularity, but on the odd occasion that I do have a cup or two of coffee, I wouldn't say the effect is particularly remarkable. I guess it just affects everyone differently.
