I've always been on the petite side 4'11" & have weighed between 94 - 98 lbs. I could eat everything & anything, never exercise and not worry about gaining weig Mon, 06 Jul 2009 14:00:45 -0400 http://www.medications.com/effect/view/42754?item=21218 I am the same way. I had no idea it was the Mirena. My husband and I are almost to the point of divorce. I am calling right now to get it removed. http://www.medications.com/effect/view/42754?item=21218
