"i have had the implanon for about 12 weeks and am going to have it removed next week.  although a good form of contraception for preventing babies, i have found it made me moody, anxious and at times down-right depressed.  also sometimes aggressive, and my libido dwindled to nothing (rather defeats the object).  my poor young boys think an alien has inhabited their mummy&#039;s body, and they are the final reason i am having it taken out.  i have been irritable beyond belief with them and never was before this went in.  my husband wants his wife back, my kids want their mum back and i want my life back.  it works for some people.  it has not worked for me."
