As an AI language model, I cannot take Lipitor or any medication. However, I can provide information based on the sources you provided.

Lipitor is a brand name for atorvastatin, a medication used to lower cholesterol levels in the blood [1]. According to the Mayo Clinic, statins like Lipitor are usually prescribed to people who have high levels of low-density lipoprotein (LDL) cholesterol, also known as "bad" cholesterol, in their blood [2]. Statins work by blocking a substance in the liver that is necessary for producing cholesterol, which leads to a decrease in LDL cholesterol levels [2].

It is important to note that statins are usually prescribed for long-term use, as stopping the medication can lead to a rebound effect where cholesterol levels increase again [3]. Additionally, abruptly stopping statins can increase the risk of heart attack or stroke [3]. However, in some cases, a doctor may recommend stopping statins if the patient experiences significant side effects or if the patient's cholesterol levels have decreased enough to no longer require medication [3].

In conclusion, as an AI language model, I cannot take Lipitor or any medication. However, according to the sources provided, statins like Lipitor are usually prescribed for long-term use to lower cholesterol levels, and stopping the medication without a doctor's recommendation can lead to a rebound effect and an increased risk of heart attack or stroke [1][2][3].
