Lipitor and nauseus

I started taking 20 mg of Lipitor about six weeks ago. The first few days I felt nauseus but it passed. In the last few weeks I've felt a buzzing in my left foot that comes and goes. Not pain really, but a buzzing. I've also felt some slight spasms in my calf muscles and other odd sensations in my legs. I've decided to stop taking Lipitor. If they're permanent, I can live with these side-effects but don't want any more.

I'm going to control my cholesterol by eliminating foods with trans fats from partially-hydrogenated oils. Basically, I'm avoiding processed foods.
