How long will it take to see results from Accutane?

I have been taking Accutane twice a day for 3 months now (starting on my 4th month). I haven’t been taking my morning pill with food because I don’t eat breakfast. However I always take my second pill right after dinner. I have not seen much results yet. If I start taking my first pill with a tablespoon of peanut butter or something high in fats, how long will it take for me to see results? Have I wasted taking it the last 3 months?
