M.I.A., Drunk and in Denial: Worst Grandmother of the Year?

Nikki and Paige claim their mother, Leigh, is an alcoholic who has "gone missing" at least 40 times, abandoned them as teens in a foreclosed home without electricity or running water, and is drunk around her grandchildren. But Leigh says she's a "functioning drinker" and can turn off her drinking whenever she wants. Leigh is a bartender, and her daughters say if she's not working, she's there drinking. Nikki says she shouldn't have to bring her children into a bar just to see their grandmother. Will Leigh listen to her daughters and take Dr. Phil's help?
