Caffeine Free Day 2

I was a little slow getting up at the beginning of day 2. I am not sure if it was from sleeping on the couch or the caffeine being purged from me. Did OK over the course of the work day. Headache kicked in at 2:30 again. I took some pain meds to try to compensate. Headache came back at about 7. Stronger than on day 1. I started to fall asleep in my chair while watching Deadliest Catch. That is the biggest indicator that something is wrong that I can think of. Spend a second night on the couch and went to sleep at about 10:30.
