Can't put in words how much better I sleep after moving to decaffeinated coffee.

I do like a nice coffee but I'm content with instant[1] decaf (and even if I have 10 cups a day it's not more caffeine than the equivalent of a single cup of caffeinated coffee).

Not spending £3/$5 a day on coffee helps too. It means I'll pay my mortgage off 2 years early.
