I've been an addict off and on for most of my adult life. But it started much earlier.
I remember when I was just a child - a child by grabthars hammer! - when in the basement of the Lutheran church ('cause all "good" Lutheran churches have a basement) other addicts would give me some . . . CAUSE THEY THOUGHT IT WAS CUTE!!!!!
I never had a chance!
Here's an excellent article about caffeine.
An excerpt about overcoming jet lag too!
There are as many different jet-lag remedies as there are
seats on a trans-Pacific flight. But one approach, outlined in The Caffeine
Advantage by Bennett Alan Weinberg and Bonnie K. Bealer, involves abstaining
from caffeine for several days before traveling, then dosing yourself with small
amounts of coffee or tea on the day you arrive to stay alert—preferably out in
the sunshine—until your regular bedtime in your destination. (During weeks of
global travel for this article, it worked for me.)
