Explanation:

Internal influences on alcohol consumption are factors that come from within an individual. One's feelings about oneself (self - esteem, self - perception) can be a very powerful internal driver. For example, if a person has low self - esteem, they might be more likely to turn to alcohol as a coping mechanism. While opinions, past experiences, and likes/dislikes are also internal, feelings about oneself often cut deeper and can more directly influence behavior related to alcohol consumption.

Answer:

one's feelings about oneself
