Am I taking Accutane with enough fatty foods?

I was told by my dermatologist that I need to take accutane with a lot of fatty foods. Whenever I have a meal, I immediately take my pill and take it with a scoop of peanut butter and then a fish oil tablet. Do I need more or is this enough? I have had almost no dryness on my face besides on my lips and have been on the medicine for roughly 4 months now at 80 mg a day, with 81kg being my weight.
