Day 1: Fasting from coffee and cookies

So, I'm curious to see if the energy I still feel at 9:45pm after a full day with kiddoes has any correlation to the fact that I had no coffee and no refined sugars today. Now I consider myself rather healthy, not totally, bc I do like my morning cup of Joe and I also like my post-dinner cookie or ice cream or some other sweet. But I have been noticing that I have been really extra draggy throughout the day, and I can see the effect of caffeine on my moods and so I've been wanting to try and cut them out, but it takes more determination than I generally have. So, we'll see how long this lasts, and how I feel...
