We cannot simple terminate a behavior without feeling the vaccum of what it has left behind. This vacuum is what makes the continuation of a habit so probably. When the habit fulfills a need then we have an addiction. An addiction is a habit with a unique physical feeling. Habits on the othre hand can simply be repititious time wasters.
Addictions have some affect on the physical body that pleasure arises from for the addicted.
If we go back to the previous discussuion we find that in fact anything we place value upon is in essence an inner choice that we allow ourselves to feel about a person, place or thing. Therefore all addictions are self manufactured. There can be no such thing but a self-manufactured addiction. First of all we must limit physical addictions to those addictions that exhibit physical symptoms of withdrawal upon the termination of the addiction. The body had adjusted in such a way to the drug that without it the body ehxibits symptoms of illness such as nausea, vomiting, chills and various other reactions.
