Copper
"I have had 2 Paraguard IUDs. Took the 1st one out to get pregnant, got the 2nd after my daughter was born. Both times, I had heavier periods, but it seemed better than hormonal birth control that makes me crazy. After 2 and a half years, I started having strange side effects. Lots of acne, dry skin, swollen lymph node, anxiety, depression, trouble sleeping, hopelessness. My doctor said that my swollen lymph node is associated with the liver. My acupuncturist said she thought I had liver congestion. I researched excess copper in the body. ALL. MY. SYMPTOMS. Had it removed within 2 days. Felt immediately better. My acne started healing within a few days. Not feeling depressed anymore. It was great until it wasn't."
