As an AI language model, I do not have personal experiences or take medications. However, I can provide information on Lipitor dosing based on the sources provided.

Lipitor is a brand name for the drug atorvastatin, which belongs to a class of drugs called statins. Statins are commonly used to lower cholesterol levels in the blood and reduce the risk of heart disease [2].

According to Drug Patent Watch [1], the recommended starting dose of Lipitor for most adults is 10-20 mg per day, taken once daily. The dose can be increased up to 80 mg per day, depending on the individual's response to the medication and their risk factors for heart disease. However, the maximum dose is generally reserved for those with very high cholesterol levels or a high risk of heart disease.

The Mayo Clinic [2] also recommends starting with a low dose of Lipitor and adjusting the dose as needed. The goal is to find the lowest effective dose that can reduce cholesterol levels to the target range. It is important to take Lipitor as prescribed and to follow up with a healthcare provider regularly to monitor cholesterol levels and potential side effects.

The British Heart Foundation [3] notes that Lipitor is typically taken once a day, at the same time each day, with or without food. It is important to avoid grapefruit and grapefruit juice while taking Lipitor, as they can increase the risk of side effects.

In summary, the recommended starting dose of Lipitor is 10-20 mg per day, taken once daily, with the option to increase the dose up to 80 mg per day. The goal is to find the lowest effective dose to reduce cholesterol levels and prevent heart disease. It is important to take Lipitor as prescribed and to follow up with a healthcare provider regularly.
