This time I had no new environment to adjust to.
So this time, it's digestive. I won't do TMI. All I'll say is about an hour after I got up I was back in bed, running a low fever and dreaming fitfully that I had to go down and get a new package of toilet paper as we were almost out in the bathroom.
I'm rather glad that the tile guys didn't show up today.
Now I'm headed down stairs for more toilet paper and a cup of tea.
