On step 2.
Missie, I would change the drink to break the habit. If you automatically do coffee with sugar either out the sugar out of reach so you have to consciously make the effort to get it (like the top shelf of the highest cupboard) and have the sweeteners handy or do as Lizz says and try some of the herbal stuff. If you've a sweet tooth the mint teas are good and some of the celestial seasons are good too. Cambridge now doesn't prevent you having any teas so take your pick!
Dont nut worry about what's done just keep going to what's next. You'll break the habit, I used to have tea with sugar now can't stand tea sweet!
