Go my Maths-Fu!

( I've been baking cakes. )

So maybe they do work.

Last night, due to staying up too late to make cakes, I forgot to put my new mouthpiece in before falling asleep.

I didn't think it had been doing much good sleepwise for me - I'm mainly doing it so that bed-partners get some shut-eye too.

The device does do me some good. This morning, upon waking, I felt like a zombie (and still do). So it looks like not snoring all night is good for me.
