I'm 32, from the North west of the UK and I'm an addict.
I quit my Lego habit circa 93-94 sometime before my teens and I've been clean for a good 15 years or so until recently when I started small with Series 10 minifigs before progressing to the modular buildings. Now I can't stop, I'm spending fortunes every week!
Recently I've been trying to find all my old Lego sets and whilst searching around the attic today I came across this which I thought you all might like:

I also found instructions for the following if they're worth scanning;
6018: Dragon Boat
6848: Mechthing?
6693: Garbage Truck
6883: Spacebuggy thing?
6679: Black Thunder
6034: Haunted Gate House thing?
6260: Treasure Island
6450: Police Light and Sound
6930: Lunar Base
6353: Coast Guard
Sorry, don't know the official names of some sets
