Felt pretty bleh all sunday long (for those not aware, "Bleh" is a technical term representing a point somewhere between healthy and sick), and as a result, basically hung around the house all day and read. I begged off on dirt bike riding, and was planning on skipping my hockey game until the last minute.
I think playing the game was the right move -- my headache cleared up immediately after I started playing. Ended up being a decent game -- we won 6-4 -- but I felt like I was running on about 50% power. There was one goal I should have gone back for, but didn't, because I was tired, and because I thought it was going to be icing.
After that, got home and had some carrot cake, which was the most substantial meal I'd eaten all day.
