Insatiability is a topic frequently discussed in addiction circles. A Tenement Halls lyric (although my favorite version is by The Shins) and ubiquitous AA quote exemplify the idea:
One is just too many, yea
You know twenty is never enough
Avoiding the first drink (or indulgence) is most important because JUST ONE will send you over the edge. You have no control or power over your drug use (See Step 1) and this slip will invariably lead you down a road of many many more drinks/indulgences because, as stated above, the next twenty indulgences will not be enough to fill the void.
Put the drink down
Hang up the phone
Explore the void instead
It's a much more productive use of your time.
