My experience is pretty much the same. I sleep and function just as well (or badly) without caffeine now as I used to do with several cups of coffee, before I quit (2 years ago). The big bonus for me is in the mornings. I don't need several cups of coffee to wake me up anymore. When I get up I am as awake as I used to be after breakfast. Be careful when you try to drink it again. One cup of coffee is enough to get me from a hard-to-focus-after-lunch-dip to fully awake and focused. If I drink another cup I become all jittery and have symptoms resembling a minor panic attack. Good luck!
