What happens if I quit when I die? Two to three liters a day, and this life is better when I limit coffee definitely applies to you and others who are challenged before they find their awakening. I would be nutty too if I consumed it at the levels described here, and then have to go through this long detox. I grew up around drug addicted people back in the olden days when they were called junkies. This was a terrible addition, but I don’t see coffee drinking going out of style for the foreseeable future.
