Implanon
"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'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."
