I've had mine for about a year and a half. I didn't have any side effects until about 3 months in. Hair loss, headaches, acne, fatigue, depression, anxiety, weight gain (about 35lbs so far), back pain, greasy hair. I think that's all of them. My family is trying to convince me that it's all my thyroid even though I got tested for thyroid disease last year and nothing. I'm hoping to have mine removed within the next week or so. No insurance, so I have to find a doc willing to do it for a small fee. I can't gain any more weight. Diabetes runs in my family and I don't want to be the next one. Did I mention that I look like I'm 6 months pregnant????
