No consultation with the doctor. My levels dropped within 2 to 3 days. My cholesterol wasn't too bad before I started statins, and I knew when I stopped taking them that I was due another blood test 4 weeks later, so would be able to see if I had done any damage. On that blood test my cholesterol was worse than on statins but better than before statins. My nurse said it was up to me but suggested I try the lower dose ones (20mg instead of 40mg). I nodded but haven't taken them, again because I will be having yet another blood test in August.
