"i am 22, no prior children, i have endometriosis &amp; was told mirena was the best option. the implementation process was hell. the worst pain i have ever been in. i fainted &amp; had to have a friend pick me up. i left it in for 10 months. within those 10 months i&#039;d gained 18 pounds (on a 5 foot tall person that&#039;s horrible), i was moody, had the worst cramps, hair loss, acne, horrible headaches, the appetite of a sumo wrestler, &amp; didn&#039;t want to do anything. i felt lazy and borderline depressed. they don&#039;t tell you those side effects for obvious reasons. yesterday i finally had it removed. being traumatized by having it put in i about made myself sick with nerves. the removal was quick and painless and i already feel like myself again."
