"i got the arm insert because i have had bad experiences with estrogen based pills on the past and since it uses a different hormone and has little chance of adverse reactions i felt good about the decision. however i seemed to be part of the 3rd of the population that had side effects. i had a little over 3 months and it was miserable!! 5 pounds in the first week and over 15 since, not to mention the awful mood swings, i have never had a history of depression but while on it i would randomly feel miserable, like the hopeless kind of depression, i broke out and just generally wanted to crawl out of my skin, i had it removed yesterday, felt the same as going in and i&#039;m hopeful my body will return to normal with time."
