CanCan,
I find myself in the same situation as you. I think what has helped me the most is to limit the servings I have available to me. I have also found new things to replace bad sugars for my "sweet tooth" I recently discovered that if you cut up bananas, drizzle them with honey and then put a little cinnamon on them, it helps a ton! It is just what I need and tastes fantastic! Then last months I did the 21 day sugar detox challenge (for your ref.: timreviews.com/21daysugardetox) ...it was so hard in the beginning, but in the end it became easier to resist sweets.The cravings, if any, are now so slight that they are easy to resist. Even coffee holds no appeal for me now as I like mine with sugar.
I think the most dramatic change I experienced is that I actually ease to sleep at 11 p.m. and stay there without waking up several times in the evening. Before I used to sleep at 2 a.m., wake up several times at night and get out of bed at 9 a.m., feeling cranky and exhausted.
Good luck.
