For a good couple of years or more, I've been steadily putting on more and more weight without trying, to the point of being nearly three sizes up from my "normal" size. Then, last month, I had my mirena coil removed and since then, I've definitely lost weight. All along, while I had the mirena in, I suspected it was causing me to put on weight - just the way it was making me feel, physically. I'm not going to fall through a crack in the floor and I don't know if I'll ever be a 12 again, but I now have more energy again and my clothes fit me better. Relief.
