Hubby and I took Lipitor for several years with no problem. Slowly, I became more and more foggy headed. Finally I got to the point that I told my husband I shouldn't be driving as I couldn't even figure out what I was doing or where I was going! After reading several articles about Statins, I stopped it cold turkey (which I know I shouldn't have) and within a week I was back to 'normal'. Dr wasn't too happy about it....but at this point he doesn't have a choice, it is my life and my body I know what works and what doesn't. I am now enrolled in a 13 wk program trying to learn better eating habits and lose weight.
