Visualisation of addiction (Evil Monkey)

Hey everyone,
I wanted to know if anyone had ever tried to visualise addiction/urges to PMO as a thing (like an animal) to help you combat it?

I went to a class to combat nervousness/anxiety and one of the ways suggested to deal with it was to visualise your fears/nerves/doubts as a creature. Then because you can condense all your bad feelings into one simple thing, you can fight it off using your mind. I decided to try to apply this to my addiction and it kind of helps.

I think of my urges as a monkey (light brown with mangy hair) that takes over my brain and body and makes me debase myself.
Now when I get urges I try and think of it like a monkey trying to get hold of me and I can try and fight it off. So far its gone well.

Does anyone else do this?

Thanks,

Warthog
