Here is an idea from a book called the Writer's diet...since you clearly are a writer and turn to it as a coping tool....this helps me work out what I am really craving..because it's easy when some random ****** feeling comes up to assume that the answer is drink/drug/food/your addiction here...when actually often it's about something else, we are just used to addressing every issue the same way..so, when a "craving" comes up, first stop and ask (and write out the answers in a journal or here or wherever)
The Four Questions - Before you eat, ask yourself: Am I hungry? Is this what I feel like eating? Is this what I feel like eating now? Is there something else that I could eat instead?
Except insert your craving or addiction in place of hunger/food.
I use this alot to get to the heart of what I am really feeling, and which feelings I am really trying to bury, and to find better ways of addressing them
