These were in .ru and pretty shallow, apart from that it was several years ago in the middle of other chat-like discussion. Idk how to search, if these threads still exist today. Guys reported that flow is inescapable for them too after some time; that it is quite depressing when you have to socialize; and that it is [arguably] not so productive overall if taken objectively.
I've decided to roll with the punches and just work all-day, but take more days off. That way I can just go straight from flow to bed (with a few walks throughout the day). But I'll try to make sense of the sibling comments as well. Or maybe I just need to get better at napping again (right after work - a great reset button).
If you have links to other discussions of this, please share :)
