congratulations on the coffee culling. It is very hard. I found the only way to do it was to quit completely - I couldn't say "I'll just have one cup, and nothing after 11 AM" or anything like that, because if I had one, I would eventually have more.
It might help to think of sugar this way: we aren't designed to eat so much sugar as is added to our foods. The bacteria in our gut should be of certain types, but when we eat sugar and simple starches, which are very easily digested, certain types of bacteria that feed on sugars grow to form an excessively big population in our guts. All the bacteria there take substances in, metabolize them, and excrete byproducts. These byproducts commonly pass into our blood stream, the same way nutrients from foods broken down in our guts passes (through the small intestine cell walls), and once in the blood, they have access to the whole body, especially the brain and other parts fo the nervous system. These substances can have neurological effects. The byproducts of sugar-eating bacteria cause us to crave sugar. Some of this is accepted as fact, and some is I think hypothetical.
When I quit sugar, I stopped craving in about 2 weeks, but for some people it's longer. I quit absolutely; I wouldn't even buy anything if sugar in any form was listed as an ingredients.
Beth - Wishing you a restful sleep tonight
