I will say that this was one of my concerns at first, however, the further I got into phase 1, I weened myself off the amount of coffee I had and creamer. Eventually, I could make it through the days without it and it feels great!
Just stick with the phases and it won't be an issue! I did have to drink coffee in the beginning though. I went to espresso/coffee and almond milk or soy if you are going to a coffee place. However - eventually I didn't need that coffee fix!

Thought that may help those coffee addicts.
