Mainstay symptoms and conditions

My mother, in her late 70s, was on Lipitor for some years. She has been taken off the Lipitor when blood tests showed gross abnormalities. She is on a Vitamin B12 therapy for severe anemia and other medications for the complications that has caused. One of the most obvious signs that things were NOT right with her was her rapidly degenerating MEMORY. It was scary. I told her she HAD to address this to her doctor. It was part and parcel of the effects of Lipitor.
Now, I was on Lipitor for 2/3 months...I immediately got what my doctor NOW has called Restless Leg Syndrome. It never went away after stopping the drug (6 mos ago). I am BACK on Lipitor and immediately upon taking it again, I started getting a worsening of Restless Leg, which inclucded severe and many nocturnal charlie horses which would awaken me throughout the night. I have only been on Lipitor for 2 months now and I am noticing muscle "tightening" in my arms (from the elbow down), too. I was given Quinine Sulfate for the Restless Legs...which I don't believe is in itself a separate disease, but a side effect of the Lipitor. I also have hand tremors. (Nerves or Lipitor?) Now, I became a vegetarian, who eats NO red meat (ok, a bite of a burger a few times a year...lol), uses soy products, veggies and beans as the mainstay of my diet. I have excluded, over the past 10 months, all saturated/trans fats and cholesterol from my diet. My cholesterol readings are like a ping-pong ball. Good, too high, too low, good, too high. I'm between a rock and a hard place re taking the Lipitor. My family is genetically predispositioned to higher than normal cholesterol levels. Yet, the doctor feels the enormous stress in my life during these past 10 months (which hopefully will start to disipate within the next month) has caused the cholesterol to be high....the higher readings began with the increase of stress.
What does one do? Is the muscle cramping and the inability to sit down for more than 15 mins a serious issue? Does it get worse? I assume it's time for a second opinion. It's a Catch 22: each side-effect can be attributed to yet another "disease" in itself. I, like most of the people on this site, have attributed most of my symptoms to "getting old".
