Yes, I'm exactly the same. I am still working (from home) which is not much different for me. However, there isn't the usual rushing about everywhere, particularly at the weekends, when I used to try & cram everything into a couple of days. Shopping is now done online, no going out for dinner, so not having to get ready to go "out out", not visiting relatives, other than to drop shopping off for parents, at leisure.
I think it's the slower pace of life that is making me feel sluggish. I'm still trying to exercise & run but not putting any pressure on myself - if I feel like it I'll do it, if not, there's always tomorrow.
But, I am definitely finding it harder to get up and motivated in the mornings.
