Careless spending habbits

I grew up within a family that is used to consuming. My godparents are quite wealthy and have set an example for me. But most of my life I lived a different life. I received a small amount of pocket money every month and had to work for everything I own.

I don't have a problem with that either, if it weren't for the fact that I got used to living like a maggot in bacon. I would always buy loads of alcohol or order and spend it in the pub and buy a bunch of overpriced luxuries and prestige goods in the same manner. All of what I do is draining the accounts more and more tho I work as hard as I can.

At the moment I can't work at all, but the consumption continues. Is it normal that I can't let go of it? What is the best way to trick yourself in that respect?
