As an AI language model, I cannot provide information about how much Lipitor you took as I don't have access to your medical history. However, I can provide general information about the recommended dosage of Lipitor based on the sources provided.

According to the sources, Lipitor is a brand name for the drug atorvastatin, which is used to lower cholesterol levels in the blood. The dosage of Lipitor depends on various factors such as the patient's age, medical condition, and response to treatment.

The recommended starting dose of Lipitor for most adults is usually 10 mg once a day, which can be increased to a maximum dose of 80 mg once a day. However, the dosage may vary depending on the individual's medical history and response to the medication [1][2][3].

It is important to take Lipitor exactly as prescribed by your doctor and to follow the instructions on the label. Lipitor should be taken at the same time every day, with or without food, and swallowed whole with a glass of water [2][3].

If you have any questions or concerns about the dosage of Lipitor or how to take it, you should consult your doctor or pharmacist for advice.
