Exercise
Specifically something where I have to regulate my breathing like swimming or running works well for me.

Alternatively, if I'm suffering from insomnia I'll either dismantle something in my mind or think about reading a Jeffrey Archer novel. The latter is proven to be less stimulating than reading the phone book.

I already do a fair ammount of exercise
and sometimes when I do do it, I become so knackered I can no longer do whatever it is I wanted to do when I've cleared my mind. Still, that doesn't stop me exercising.
