Did you read through any of the threads on AVRT?
Any thought , feeling or image of future use is AV. The AV is the desire for the pill's voice, the Beast's voice speaking' to You in your own voice, IT uses your thoughts and your own personal vocabulary to drive You , try and convince You to use again.
Using AVRT shows how to separate from that desire and recognize that voice as not You. To see that constant feeling as not You ,but IT.
You know it is not 'one more' , your own experience shows you it can never be one more, that is a lie the AV is feeding you .
You can acknowledge that 'feeling' and then dismiss and disown it. It doesn't have to be yours, if you don't want it to be.
