High desire related to addictive personality?

[nightrunner]

I have been wondering about this. I have an addictive personality. I used to smoke, finally quit 3 years ago. Now I love chocolate. I also have gotten back into collecting audiophile CD recordings. I have noticed that when I like something, I want more of it. This does not affect me with drinking or other bad things. I have a six pack of beer thats been in the fridge for 4 months, even though I really like drinking a good beer. Do you think HD and addictive personality could be related? This could be a good discussion!
