Anyone here with high cholesterol and on Crestor?

I am not seeking medical advice. I have already been to the doctor, she says my cholesterol & triglycerides are high and she wants me on Crestor. My insurance co-pay is $50. I asked for a generic drug, but she is insistent on THIS particular drug. I have taken Lipitor in the past which made me nauseous and caused muscle pain. I know it’s silly to pay a doctor for their medical expertise if you aren’t going to do what they say, but I just have some real concerns about the side effects of this drug. What other choices do I have but to either take this drug, take nothing, or find another doctor who is not perhaps getting kickbacks from Astra-Zeneca??
