I found the quote from Trainspotting about getting off heroin that reminds me of what getting off caffeine has been like:
"I'm cleaning up and I'm moving on, going straight and choosing life. I'm looking forward to it already. I'm going to be just like you. The job, the family, the fucking big television, the washing machine, the car, the compact disc and electrical tin opener, good health, low cholesterol, dental insurance, mortgage, starter home, leisurewear, luggage, three-piece suite, DIY, game shows, junk food, children, walks in the park, nine to five, good at golf, washing the car, choice of sweaters, family Christmas, indexed pension, tax exemption, clearing the gutters, getting by, looking ahead, to the day you die."
