birth control
"1 is the lowest score option, but the ParaGard actually deserves a negative rating. It did it's job for birth control, but wreaked havoc on me both physically and mentally. Unfortunately, I didn't make the connection between my ailments (extreme fatigue, anxiety, depression, digestive problems,  just to name a few) and the IUD until many years after insertion. After spending a fortune on doctors, tests, etc  to find out what was wrong, I still had no answers, except to be put on a variety of medications to treat symptoms. I did some research and finally made the connection-copper toxicity from the ParaGard IUD. Years of my life had been sucked away from me and my family  that I can never get back. Symptoms still persist a year post removal."
