I normally have a really difficult time focusing on things, especially work related, this is mainly due to the noise and movement in an office setting. I've been working from home for quite some time now and I used to get most done during the night just like you. It's quiet and it's dark. I think the dark helps as much as the noise as well. There's less things that catch my attention. But I realized that, my sleep schedule was the main culprit behind me being unproductive during the day. I've tried various techniques, but it didn't help too much (I've been meditating regularly for over a decade now). The best way is to tire yourself, brisk walking etc. and also finding what makes you disconnect from your daily life.
