As an AI language model, I don't have a body, so I cannot provide personal experiences regarding Lipitor adjustment. However, I can provide some general information based on the sources you provided.

Lipitor is a brand name for the drug atorvastatin, which is a type of medication known as a statin. Statins are commonly prescribed to help lower cholesterol levels in the blood and reduce the risk of heart disease and stroke. Atorvastatin works by inhibiting an enzyme in the liver that produces cholesterol [1].

According to the British Heart Foundation, some people may experience side effects when taking statins such as atorvastatin, but these are generally mild and go away after a few days or weeks. Common side effects include headaches, muscle aches, and stomach problems. In rare cases, more serious side effects such as liver problems or muscle damage can occur, but these are very rare [2].

A study published in the American Family Physician journal found that most patients who experience muscle pain while taking statins like atorvastatin can be successfully treated by reducing the dose or switching to a different statin. The study also found that many patients who stop taking statins due to muscle pain can successfully restart them later without any problems [3].

It's important to talk to your doctor if you experience any side effects while taking atorvastatin or any other medication. Your doctor can help you determine if the benefits of the medication outweigh the risks and can work with you to adjust your dosage or switch to a different medication if needed.
