I thought getting up early and exercising was going to fill me with energy and make me feel more awake in the mornings. (perversely it seems the more sleep I get the sleepier I feel through the next day and the nights when I get crap sleep I feel wide awake - which I appreciated more in the earlier days when ZOO wasn't sleeping but now that she sleeps well through the night...). However it appears that my power walking (trying to be nice to my sciatica) just makes me feel sleepy and body tired ;)
