I don't use social media. So I can't get distracted by it. I only visit about 3 websites regularly and I'm old enough to be able to do what I'm supposed to do when I'm supposed to do it. But if it helps people, then it's all good.
The reason I used Do Not Disturb is if a mate is drunk late night and engaging in a bit of texting logorrhoea, so I turn on DND for him until the morning.
