I have shades and have no issues with the light anyway, but it's tough to get the kids in bed before 23:00, not to mention to get them up at 07:00. I've found that after 3 months or so without darkness to speak of it's getting on my nerves, but for that I need to be at higher latitudes.
I don't think my sleep pattern is much affected by daylight. I struggle when I change time zones. Tomorrow I move 9 hours, and I'll have a week of insomnia again.
EDIT: No darkness, but still dark enough for some meteors: 2018-06-20 00:05UTC
