Nothing quilty is going to happen today

I am just beat today, for no apparent reason.  I felt fairly rested this morning, but shortly after arriving at my client's offices, I felt like I could have gone to sleep right on my laptop.  In spite of numerous cups of coffee, I just could not get my energy level up and my head feels like I'm in a fog.  I got on the treadmill when I got home, which usually clears my head, but it had no effect at all.  I feel perfectly fine, have no sinus problems, got enough sleep last night, so who knows.  I did have an 80 mile round trip commute, which does tend to zap my energy a bit, but usually not this bad.  So, there will be no quilting taking place this evening.  At best I will work on some dishcloths while watching TV.  Hopefully I will have something more exciting to post tomorrow.  I did think about some quilt designs while I was working today :-).
