Coffee!

So, its been a while since I've been back on the wagon, and its been a little over a week since my first adjustment in a REALLY long time. Things seem to be going well, however with that being said, I've noticed along with my "forcing" myself to drink my required amounts of water for the day, I've also had the incessant need to drink coffee.. its a bit unnerving. Now I have always loved coffee, but it seems these days I've been drinking it more often. Now mind you I'm a black coffee drinker, so its not like I'm even craving the sweet stuff.. but I'm thinking I probably need to slow it down.. I bought a few boxes of teas to try.. I am just wondering what my obsession is all about?
