Doubt signifies that the craving is still a problem; it exerts a pressure on you through the possibility that it might arise again, but that possibility is it’s arising, it gains access to you through doubt.
You might still give in if external circumstances pressure you too much in unimaginable ways. There is a doubt.
One must uproot the root of the problem, because the problem is not alcohol or social circumstances,it is the desire for the ‘wanting of pleasure’.
If that desire and lust is not wanted, if the prospect of bodily pleasure is not wanted, then nothing secondary to that can pressure you in anyway. No sight,sound,taste, touch,smell or thought can exert any pressure because one has given up the ‘desire and lust’ in regards to the possibility of pleasure from them.
You wouldn’t have to try give up all the various things in the world that one has craving for ,because they all exert pressure on you only because you WANT or welcome the ‘desire and lust’ in regard to the possibility of getting pleasure from them, which is actually not possible.
Stop wanting the wanting, and you will have uprooted even possibility of craving, let alone secondary addictions.
There is a difference in no longer delighting in a thing because one simple gets bored with it and no longer delighting out of wisdom;
When one desire ends, yet is replaced by another, the delighting in the possibility of sense pleasure is still present, it just changes its content i.e one might no longer desire alcohol because the pleasure was not found there any more,but still one seeks a sense pleasure elsewhere.
Like, for example , as a child you like certain music and then, as you grow up your interests change, music becomes less important, or more refined(proliferated), one no longer finds the pleasure there as one use to.
This is not a sign of wisdom or the result of practice, but instead it’s the sign of being unsatisfied, being bored, and a sign that one’s desire and lust is now proliferating into other more complex particular desires. One craves now here and now there.
The loss of interest in one particular sense object, does not mean craving is diminishing, it just means its moving onto something else.
The loss of interest in the desire and lust in regards to the possibility of accessing the pleasure desired by the senses, that is a sign that one is headed in the right direction.
