A large percentage of "I need this drug/drink to function" people eventually face some measure of change in their lives that force them to start learning how to manage themselves without outside chemicals or medication.
It may be you, it may not be. The point is, don't get set-in on "policy" because you may want to change your life and need to understand that the discomfort of change is only temporary and the brain rewires itself to new conditions.
It does get old after a while.
edit: I am fully prepared for the reflexive defensiveness that this topic produces. Please look up psychological addiction even if you feel offended by the very notion. Especially if you feel offended by the notion. Ask me how to get out if you're starting to feel that trapped feeling and wondering if things ever get better.
