I drink about five strong mugs of the stuff per day. I start the day with two mugs, one with lunch, one with dinner and there is usually another one in there somewhere.
If I am to be a functional human being that has to happen. Maybe it is unhealthy, but it is not going to change any time soon.
Unless you have some cocaine to share. No? Then back out with you to the back garden until you get me coffee. I get three unbroken hours of sleep per night, seven in total usually. Chemical assistance is going to continue for quite a while to come, I suspect.
