I have insulin resistance (PCOS), which comes with difficulty losing weight no matter the effort, acne, low energy, etc. I cannot lose more than 10 lbs EVER and I am 40-45 pounds overweight. I'm also pre-diabetic with family history of diabetes. I'm at 5.8 a1C and fasting sugar is 140. I'm on Metformin 1000mg but I am building tolerance. The doctor suggested Bydureon and increasing Metformin to 2000 mg. She told me to think about it but I'm not sure after reading the experiences/effects. Having nausea/diarrhea constantly sounds horrible and I am not a needle person. Plus, I've heard it is super pricey. Is it worth it??
