Too Tired

I should put a new post on here, but I think I am just too tired to cope with it this evening. Maybe later.

Hitting the Wall

I don't know why it happened but yesterday, Sunday, I found myself in the blue zone (see the chart) and ended up taking a nap from 4pm to 8pm and then going back to bed at midnight and waking up this morning feeling much the same way.
Hopefully as the day goes on I will feel better.
