If you're having issues keeping your carbs at a healthy level, try adding some colorful fruit. If you're worried about sugar, snack on low sugar fruit like berries (blueberries are oddly amazing for this.)
I sadly don't know anything about coffee, but definitely drink coffee and tea over soda. If there is a Teavana in your area, you may want to hit them up for delicious tea (warning: it gets expensive very quickly.) And if you must have sweet, opt for honey or natural agave nectar. They won't give you so many cravings, they're natural, and they will help you ween yourself of refined sugar without feeling so deprived.
Call me cael if caeliumspecto is just too long.
Also, though I would never say anything I thought would hurt someone, I am not a health expert.
