Tired at the end of the day?

Does anyone else fine they are just exhausted come the end of the day? I am sleeping well, and I am fine when I am working (I work from home most of the time, so it's not like there is lots of social interaction to burn me out - just occasional zoom meetings).  I don't have any problems with my energy, but once I have finished, walked my dog and had something to eat, I just have nothing left in the tank.  Literally all I want to do is go and sit in bed.

I used to indulge in my hobbies and special interests in the early evening, but they have all just gone by the wayside as I just have nothing left, nor much motivation to do anything as I am so tired. I just sit in bed with Apple TV on.

Does this resonate with anyone else?  I never used to have this problem, but I just seem to have no energy at all these days once work is done.  Exercise doesn't seem to help much either.
