3$* 5days * 48weeks * 40years (65 years - 25 years) = 28,800$ before investments.

However, caffeine is a larger problem. It's very additive with strong withdrawal symptoms, but giving it up for 6 months has significant mental health benefits. Unless you enjoy black coffee it often adds up to several hundred calories per day.

Aside from sleepiness for a few days and a (lack of) caffeine headache for a day, what are the strong withdrawal symptoms? I honestly don't think there are any and have never figured out why some people are so against coffee. If I'm wrong, please tell me what I am missing. Thanks.

I agree the sugar and milk/creamer add a fair amount of calories to your diet.

You know, Erdos (great mathematician) said that minds like his had to be constantly caffeinated (and sometimes involved with the potent psychadelic) to maximize their potential. Caffeine is good for productivity, or Mate (Yerba Mate).

In the short term the symptoms are headache, fatigue, anxiety, irritability, depressed mood, and difficulty concentrating. That generally lasts less than a week, but can be very difficult for heavy users.

However, because of how it integrates with your sleep patterns it can take 6 months for normal alertness levels to show up assuming total avoidance. Healthy individuals with reasonable sleep cycles should feel alert for the vast majority of the day without any form of stimulants.
