You obviously don't have enough barking dogs, crowing cocks and howling Karaokes to gently send you off to sleep.
Seriously though, try getting more exercise like walking, so you get really physically tired before bedtime.
It does help you to sleep and just to calm down generally.
Avoid afternoon siestas for a while.
I got into the habit of having the radio on all night (music) just to drown out all the other noises. That and a few (medicinal) San Migs always worked for me.
