I've done most of these and they all help. What really helps is silicon earplugs (they warm up to body temperature and mold to fit, so comfortable I've forgotten to take them out until I'm half way to work) - a lot of my issues are I require silence to sleep and stay asleep and the modern world just isn't conducive to that at all.
