Same, and I'm trying to fight against it. I've noticed that when coming home I am not just procrastinating, but actually exhausted. Idk if it's due to concentrating all day, or something with me, but I do know that I am tired.
I've started to actually embrace it, and for the time until I get dinner, I just rest. Might sleep even. There's no point in fighting, as I aren't in the mental space to do things.
Then after dinner I'm back to do stuff, maybe even later in the night as I am more rested from my nap.
Although another take on it is that things are lot more enticed to do things when you can't/don't have them.
I am not a doctor, nor claim what I do is healthy, but that's just my experience. If anyone got tips I'm listening
