Wow... this is exactly how it felt! I definitely felt like I was "shut down" for the rest of the night. I started to feel that way earlier in the day and forced myself to fight through it because I was in a classroom of kindergartners when I noticed it and knew there was nothing I could do at that moment. Luckily the enrichment program is more laid back on Fridays... it's basically recess all afternoon... so going in and watching the kids play wasn't too big of a deal... but making it to the end of the work day and to my bed at home was all but a miracle.

Thanks for the link. I'll go look at this right now.
