Don’t believe she drank a liter of vodka every day. Nor do I believe that she drank 8 liters of Pepsi every day.
You’re right .. I mean .. that’s a lot of liquid for any one person to consume in one day; no matter what type of liquid it is.
I believe it was more medication related; in that taking the wrong dosage, or not taking it at all .. or after not taking medication for a day, people will take more the next day to make it up .. not realizing that their body may not be able to process that size dosage, resulting in a bad reaction to the medication.
