i tried to drink a gallon of water a day and only lasted about a week. i've pretty much cut out soda since i got them. i've heard large amounts of red meat and generally bad diets are the main contributors to them.
it is hard to cut out things like raspberry iced tea and lemonade. things that pretty much have all of the same shitty things as soda does.
the doctor told me that the pain is the male equivalent to giving birth. seriously though, if that is the pain of giving birth, women are overhyping it like crazy.
