My husband had quadruple by-pass surgery in 2001 specialist said it was 'genetic' narrowings. Had never had a cholesterol problem and Zocor then changed to Lipitor 40mg as a prcaution to ensure he doesn't. He is an Insulin dependant diabetic and last week he did not take the Liptior for four nights his BSL readings were immediately halved and I wonder if there is a connection. Has anyone else noticed this, I would appreciate any responses....Jan
