Ashley, welcome! And I would slowly go down to decaf coffee if I were you to prevent the headaches. Mix it in parts until you are fully on decaf.
I only drink decaff coffee now and don't notice the difference at all. Tastes the same! :)But as a result, my adrenals are much more under control and my whole life feels calmer.
Sugar...well...that takes longer to get used to, but you get to the point where real food just tastes better, with more layers, textures and freshness. Sugar starts to taste garish, somehow, lacking in real, honest flavors.
Hardest of all is to lose the comfort associations we have with starches and sugars. That is entirely within the psyche and therefore toughest to relinquish. But it can mostly be done if you find other activities that you really enjoy and that make you feel better. Like curling up with a cup of gourmet tea and a good book in a nice nook, instead of hunkering down with a tub of ice cream, a greasy Big Mac or bag of cookies.
Anyway, stay with it; we are all in this together and it really does work.
