I have experienced a totally different effect with the IUD. My sex drive is up the roof, I am constantly thinking about sex, and my body is out of control. I feel like I am in high school again. lMAO!! My husband loves it. Weird that I am experiencing a totally different experience. I am 35 and within the last 10 years I haven't been even thinking about having sex. I just got the Mirena, IUD in 4 months and within the 2 months I felt different with my hormones. I feel more happier and my sex drive is unbelievable. Sorry to hear that so many others are experiencing a totally different way.
