Ironing at 5am was what I used to do prior to taking up running again. Reason is that no little ones, and so safer. Also nice to listen to radio quietly in morning rather than be watching Monsters Inc. for the 10th time (quite good, though!).
I am going to look into two single duvet idea. Seems the most sensible. We did try double sheet with single duvet on missus, but duvet kept sliding off (apparently). Also when missus wakes up and I am a sodden heap she tries to remove duvet, but apparently I am "quite agreessive" in defending it, even whilst asleep...
