Upon waking up I have 1-2 cups of coffee, minus the sugar.
Throughout the day I have close to a gallon of water. Also, I drink Weight Watchers soda: contains no sodium, no sugar, no calories, etc... Coke zeros contain sodium, no? If a drink contains sodium I always thought it defeated the purpose of drinking it - which in my case has always been to quench thirst... sodium acts as an agent to make you drink more never actually quenching my thirst - in my experience.
As far as alcoholic beverages, my handle speaks for itself. :)
