no time/energy

pup's lost the great sleeping routine he's had for a few weeks, waking up around 5am, then falling asleep around 8-9, sleeping for 1,5-2,5 hours, then waking up, eating, playing and then another hour, sometimes two of napping in the afternoon until he finally fell asleep for the night around 6:30-7:30pm

now he wakes up at 5 still, but sleeps only half an hour on both sides of noon ((if I'm lucky) which gives me a whining crypuppy who's not happy about anything, not even sitting in mommy's lap.
*sigh* so I'm tired, really tired. No energy for doing nothing...
