"i had my mirena inserted 1/4/10 and i love it! i know everyone is different, but it has been great for me. i&#039;m 24, never had kids, and was on the pill for the past 6 years. insertion was uncomfortable and painful, but not horrid (and i have a low pain tolerance). however, my doc did give me a local (lidocain) which i&#039;m sure made a huge difference and i would not do it without.  i felt dizzy and nauseous for the first hour after and relatively bad cramping for three hours. the next day i was a bit tender, and by day three i was my normal self. had some very light cramping for two weeks and now nothing, not even my period. i did have a little acne at first, but that may have had to do with going off the pill. i&#039;ve even lost weight."
