I'll be honest, I'm not ready to give up my coffee and tea, but I've made great efforts to limit them in recent weeks. It helps cut down on the incredible number of potty breaks I find by body requires throughout the evening!
I don't bother with TV at all unless the wife is watching it, except for the occasional Buddhist / spiritual documentary on Netflix. I haven't listened to the radio while driving (except when the family is in the car with me) except to listen to chanting (thanks to Metta Forest Monastery) in two or three weeks.
I spend a little time every weekend on the computer playing games with my son, like Civilization. I haven't played any games (by myself or with anyone) with graphic violence / "adult" content in nearly five months.
As for eating, I'm only eating between dawn and noon on weekdays. Weekends are difficult because I end up spending the whole day with the family (as opposed to only three or four hours), and they tend to graze all day
... and my wife would be terribly cross with me if I didn't eat dinner with them when we're all together!
