I'm a caffeine addict and go through phases of more and less coffee. My longest stretch on zero caffeinated beverages in my adult life was about a year. The reduction for 1 to 0 coffees was brutal. Slept loads more and so much better the fist week. After a month of no coffee my sleep regressed to the same as now, drinking 4 coffees per day. Research somewhat supports this, you get used to a certain caffeine consumption and only abrupt changes in consumption produce changes in sleep/wakefulness. I wish you the best friend, but you might not find abstinence to be a long term solution.
