Do you run regularly?

Overweight by chance?

I've put on a bit of weight sunce having kids and my breathing at night is much worse than before.

You have no idea what you're talking about and it shows by what you choose to type.

It's not exclusively caused by fitness or lack thereof. A cursory Google search would show you this. It's not "breathing at night", it's literally suffocating in your sleep.

This place used to be full of intellectuals. It's a real shame.
