What about addictions?

Yesterday I spoke of creating perfect characters versus scarred characters. What about recovering characters. I personally have no dangerous addictions but I’ve heard said that the cravings never go away. Many movies show a recovered alcoholic staring at a bottle of alcohol debating how much they really want that drink versus how much more it would screw up their life. Ex-druggies often think on how easy their life was on drugs and ex-smokers still crave the nicotine years after stopping. Adding an addiction or old addiction to a character can add another dimension to their personality. It also usually covers another deep seated issue that the person refused to face and possibly still does, the reason they needed to escape in the first place. Figure that out and you can look into helping your character find inner peace.
