don't worry - i napped every day over my christmas break and since i've been back at work, i'm still having a nap when i get home from work probably a couple of times a week and at least on one weekend day as well.

i changed my work hours to start & finish earlier so i have more time between getting home & having to cook dinner & also means i miss some traffic as well. i think this has helped quite a lot.

my poor DP is wondering whether i will ever stay up past 10pm again

my theory is just to go with what your body is telling you - sleep if you need to!
