Woke up this morning feeling pretty good. The immediate "OMG, I need a smoke or 10 to make up for the last 8 hours of nothing" feeling wasn't there... At first. I hung around in bed for about half an hour just enjoying it. Got up, made a coffee and went back to bed to listen to the radio for a while - I don't remember the last time I did that. That's when it hit me like a truck. I just rolled over and closed my eyes for about 15 minutes and the feeling had lessened. Not completely passed, but certainly wasn't as intense.
I noticed that my breathing was a lot deeper than it usually is. I wasn't struggling to breathe and having to consciously take deep breaths like I usually am in the mornings. These are all good things, and I'm actually excited to see what other changes will happen in the next week or so
