She drinks to not hear the voices in her head, she drinks till that last drop is gone, till that last bottle is gone. All she can hear is the words of alcohol telling that more is better, she can only hear the words when they say more is better. She doesn't see that the more she takes the more she loses. She only drinks to end the conversations in her head. She used to be able to smile but now the alcohol has consumed her into thinking that only liquor and boozes will make her smile the way she used to. But in reality, she turns into this wreck that nobody wants to see. The thoughts use her mind as a playground and the demons use her brain as a way to mess with her and get her to do things nobody wants to do. She's always saying “this is my last drink” but you can't stop the addiction when it's an obsession and takes over your mind and every thought till you don't have control over it, till your not thinking your own thoughts and only thinking what the alcohol wants instead of what you actually  want...That's when your only hearing the words of alcohol.
