You need to get that tooth checked out ASAP. You'll feel so much better once it's taken care of.

I have NO idea why motivation changes throughout the day. I wish I did. It's 3:32 AM and I'm WIDE awake... and I have to get up for work in 4 hours. I felt like crap -- all groggy and miserable and brain-foggy through most of the day even though I got 8 hours sleep Sunday night. Now I'm in a pretty good mood, but I SHOULD be sleeping.
