"tons" is relative. But mostly I get anxious because I want to reply to any of the ones that are misinterpreting me - which is probably a lot of them - or the ones that are engaging positively. 
And I know that each of those is going to be its own rabbit hole of attention. So usually I end up with a sort of scattered and stressful few hours, which admittedly is not good!

Luckily it doesn't happen often lol.
