Sounds like the 6-week Transformation Plan could be a good starting point for you to give you some structure and get you off that coffee crutch. You can find the plan in the Natural Healing Foods book and also the User Guide and Recipe Book that came with your Bullet!
Also, check this recipe out; it might be a good coffee replacement!
6oz warm water, 1 Tbsp Superfood Superboost, 1 tsp raw honey, 1 tsp cold pressed coconut oil - Blast in the NutriBullet and then heat up more if desired. It's absolutely delicious and great for the cold weather :)
