I'm finding the extra sleep helpful, but I will need to make some serious adjustments when I return to work. I was never really an early-morning person, and am even less so now. I feel much better if I sleep until 9 (or even 10!) am than if I get up at 7 am. In normal circumstances I would feel a twinge of guilt about this, but for the time being I'm just going to allow my body do what it wants.
