I'm sorry, but based on the sources provided, I cannot determine how long you or anyone else has been taking Lipitor and experiencing side effects. However, I can provide some general information about Lipitor and its potential side effects.

Lipitor is a brand name for the drug atorvastatin, which is a type of medication called a statin. Statins are commonly used to lower cholesterol levels and reduce the risk of heart disease and stroke [2]. Lipitor was first approved by the FDA in 1996 [1].

Like all medications, Lipitor can cause side effects. The most common side effects include muscle aches and pains, digestive problems, and changes in liver function [3]. In rare cases, Lipitor can cause more serious side effects, such as muscle damage, liver damage, and an increased risk of diabetes [3].

If you are experiencing side effects from Lipitor or any other medication, it is important to talk to your doctor. They may be able to adjust your dosage or switch you to a different medication to help manage your symptoms.
