I woke up refreshed and energised this morning after 6 hours of sleep. Unfortunately the time was 3:15am.

I've tried going to bed three hours later (midnight-ish) to target a wake up time of 6:15am, but I still seem to wake up at 3:15am.

It's like I'm in a different time zone!

During Daylight Savings Time, I'd get up at that time (4:15am) and spend about 30 minutes to feed the cats, and then nap for a couple of hours. Maybe I should start doing that again....
