I too have ADHD and my in office days are so full of interruptions I just don't plan productive work during that time anymore and instead just book them full of pointless meetings.

Working at home I get interrupted exactly once a day by my girlfriend while she plays with our cat on her lunch break since she had a permanent work from home position even before covid.

A single quiet Thursday or Friday let's me out pace all my peers books of work. The company just wastes their money when they make me show up in person. I don't even by lunch or snacks out there or anything so it doesn't even support local economy. Just wasting time and money for people who can't keep their home organized enough to effectively work from.
