Hands down! Coffee is the most difficult thing for me to be away from. I am surprised how powerful the draw and how powerful my imagination that it would feel good to have a cup. And it is not just in the mornings.
Though this is not exactly comfortable, being away from coffee, I am glad to be doing the experiment.
I wonder if coffee has allowed me to be able to push myself too far, and now I am creating the opportunity to move back into some degree of balance.
