Exactly so was it before my "great break" of 7 months. I used to get up at 5, full of energy. I thought I could keep this level of energy till the evening. This was rarely the case. And it is not the case now, too. It was a boring day today, but this is depleting, too.
I should take a shower as soon as I am at home. The water refreshes me and perhaps I am then a bit more prolific in the evening.
Early to bed, early up, that's my new lifestyle. :)
