On Friday afternoon, I celebrated one week without coffee. Most of the day I didn't even think about coffee. Tea is still my best friend.
On Saturday I didn't drink any caffeine at all. My head never quit hurting except when I went for a run. I was confined to the couch watching documentaries on netflix and getting killed by Olivia in rummy.
At this point I don't feel like I need caffeine to feel awake or alert. I just need it to stave off the headaches.
