Based on the provided sources, there is no specific mention of an "ideal gap" between taking Lipitor (atorvastatin) and consuming dairy products. However, Lipitor should be taken consistently, preferably in the evening, with or without food [1][2][3].

Dairy products can be consumed at any time that is convenient for the individual, as there is no known interaction between Lipitor and dairy that would require a specific gap between consumption [1][2][3].

However, it is always recommended to consult with a healthcare provider or pharmacist for personalized advice regarding medication and diet interactions [1][2][3].
