Why are you giving it up babe? Cutting back isn't good enough?
Sometimes these things can be part of a ritual... all the associations and accompanying things (smell of the coffee, taking a break for yourself, etc) make it very hard.
There's no way I could do it. There are people in my life who have made it clear they don't want to deal with me until after I've had my coffee. I am definitely NOT a morning person...coffee is the only reason I can function during the AM at all.
