Practices such as these should be sign posts of an underlying imbalance.
Imbalance such as is indicated here can lead to cravings for extreme yin substances as well. These extreme yin substances include tobacco, alcohol, and, of course drugs.
Extreme imbalance always calls for extreme satisfiers.
Once the state of imbalance reaches this point, it is difficult to reverse. The key is to provide foods from the middle of the yin - yang spectrum which bring the subject back to balance. Unfortunately these central foods do not provide the expected kick to the tastebuds that the subject has grown accustomed to so they are often rejected as not tasting good. This becomes a vicious circle which can spiral out of control.
