birth control
"Worst thing ever! Had it in for almost a year, finally listened to my husband and got it removed. He said I wasn't the same person. Ok 
 I thought whatever.... After removing it I didn't hate him any more ( ok I didn't hate him but wanted nothing to do with him if you know what I mean).  I  realized it was making me into a crazy person and I'm back to my normal happy self. It gave me terrible mood swings! Never again"
