Ready for something stomch-churningly grotesque that the fine people at TLC just sent us? As I Tweeted on Sunday night, only a person who drinks their own urine and calls it "lemon-y" could make a person who drinks gasoline look normal. World, meet Carrie. She's been addicted to drinking her urine for over four years. She'll be the subject of Sunday's "My Strange Addiction" season finale at 10/9c. The story is really quite sad, actually, as Carrie believes it helps treat her cancer. Hit the jump for a preview/promo.

Says TLC: "She's consumed over 900 gallons of urine since her addiction began 53-year-old Carrie has been addicted to drinking her urine for four years. She drinks about 80 ounces every day, brushes her teeth with her urine, uses it as lotion and even adds it to her bath water. She’s so obsessed with it, Carrie even believes her urine treats her cancer despite no medical proof that it works.."

The season finale airs this Sunday, March 18 at 10/9c.
