I failed it! :-( I got up this morning in the cold and made my way into work with an extra can of Coke to get me through. No problems, though that can was gone in about 10 minutes. Lasted through till coffee, then after coffee, then after lunch, then around 3pm i got a very bad headache and sleepy as all hell. Bought a 1.5L of Coke that i couldn't afford and struggled through the last couple hours... And by the time i sat in the car to go home i needed something. Two cigarettes in the car, five this evening, one an hour. That's a light day for me so it wasn't great, but at least it wasn't a half pack. Tomorrow i'll space it out better. One morning, one coffee, one after work... and then i'll see. I do enjoy smoking, you know, it's just those absent-minded habitual evening ones that are a waste of money and fucking up my health. So yeah. I suck. But i did make it 18 hours, and through a hellishly busy Monday at work. Go me.
