Does feta cheese contain Potassium?!

Hey, I'm trying to cut back on some potassium. I had a blood work done recently and although my potassium is within the normal limit, its in the upper area. I was wondering what foods cut down on potassium? and how much feta cheese, like Bulgarian feta has? is it allot?

Thank you, 10 points for a good sincere, detailed non copy paste answer :)
