A great timeless article. I've been off of all forms of caffeine for about 40 years. I was thoroughly addicted to it, and in my 20's, I was drinking about six cups of coffee per day. It took me three tries to kick the habit, and the final time I quit (all cold turkey), I felt like a heroin addict (I assume). I had cold sweats, shakes, headache, and vomiting. I missed two days of work while recovering. I'll never forget how awful I felt, and it's a constant reminder for me to never go back to caffeine. I make coffee for my wife every morning, and the smell is enticing, but I can easily resist. My wife is a zombie when she wakes up, and she really needs the coffee. She doesn't seem to have an issue with it, and usually has only one cup per day. Now when I wake up, I'm alert and ready to go. Caffeine is difficult to avoid, and it's such a commonly used drug that most people do not give it a second thought. Another interesting side effect I noticed while doing coffee was the poor quality of the code I had written on the previous day. I was doing embedded assembly (6809) at the time, and each morning, I would pick up where I left off and notice a ton of mistakes. It looked like I was high while I wrote the code. Under "normal" circumstances, my code is often error free, and requires minimal debug.
