Yesterday I had 3 cups of coffee in the morning (I usually only have 1 per day) and was a bit of a whirling dervish all day, and emptied then decorated a bedroom.
This morning I had 3 cups of coffee, finished the bedroom, have done masses of gardening, now I've crashed, I've had some chocolate and cake (I needed the sugar), and I feel crap now.
All I want to do is crawl into bed till tomorrow morning.
Why did I drink a week's worth of coffee in 24 hours???
