When you stop drinking, it is normal that at times you feel peckish. This feeling arises because your body will prepare itself for alcohol in situations where you typically drink.
To understand, we look at the example of Pavlov’s dog. Pavlov was a researcher who looked at animal behavior,to understand better the behaviour of people.
The dog began to salivate when he got a bowl of food. The body of the dog was preparing in that way for the processing of food. Pavlov heard a bell sound whenever the dog food was ready. After a while the dog was so far that he began to salivate when he heard the bell alone. The body was ready for the food to be processed, while in fact only a bell was heard.
In humans, this works the same.
The body prepares itself for the arrival of alcohol in response to certain stimuli. The feeling that is created is called migration.
These incentives may be very diverse: the smell of alcohol in a particular place or situation, or it could also be linked to a certain feeling. What about you? What are your stimuli? Is it when you smell cigarette smoke? Is it maybe when you feel sad?
Recognizing and dealing with migration is an important part of learning to stop or reduce drinking. The addiction treatment site for more info on how to stop drinking alcohol.
