I was real tired and slow this morning. I think my allergies finally wore me out. It was definitely the most fatigued I've been since I started commuting about 3 years ago-my tank was empty and the only thing I could envision was laying down on a park bench and going back to sleep. I finally made it to work (barely) and felt better after breakfast (followed shortly thereafter by sucking down 2 additional bagels), maybe my body was trying to tell me something. I hope the ride home is better.
