Lipitor and migraine headaches

My doctor put me on 40mg Lipitor about 4.5 months ago. My cholesterol at that time was about 220. The Lipitor has reduced my cholesterol to about 105 but not without serious side effects that I began noticing about one month ago. I am a diabetic, BTW, but but sugars are well-controller. The first thing I began to notice is that my thighs felt cold all the time, sometimes even burning--but only when I sit down. If I put heat on them, it goes away. Putting cream on them goes away. Another thing I was getting these migraine headaches that affect my vision, causing blind spots. I've them before but never with the frequency of the way they are occuring now. The last two big things is absentmindness and extreme fatigue....whew. Well, I stopped taking Lipitor today and I feel better already. Diminished fatigiue, for sure.
