I am double glad to read this. I am pretty much the same. I just cannot work when other people are around. I tend to end up helping them on some of their tasks and do my work when they all have left. The problem is that doing so gets work done , but you get a bit burny and your, if any, social life suffers.

I have since then, done the following, found a special zone/cabin and started to make a list when I go to this cabin. This has helped on tasks that I like to do (like designing and programming) but I still have to slog through other tasks (making presentations and writing pointless documents) in the late evenings.

The guide that helped me was this : https://adhdatwork.add.org/adhd-accommodation-guide/

FWIW, liking to work at night is s very popular thing.

We are legion...
