Smart water symptoms and conditions

I have been on lipitor since Oct 2008, 10 mg. Off and on, I am very dizzy. The backs of my calves start to weaken and I start drinking Smart Water, because I think I"m dehydrated. The Smart Water does help, but today, the dizziness is lasting all day. I probably have tinnitus. My right ear occasionally has a loud ringing and today a little pain and feels as though it has water in it. I am going to call Life Extensions and speak to their health advisors and try something naturpathic. I am soooo scared, because I have 50% blockage in my carotid arteries. Any advice out there?
