Is it okay to take Accutane every two days?

I was just on accutane 40 mg a day for 6 months and 80 mg five days of that, but taking away the occasional day i missed ive only taken a little over 105 mg per kg cumulative dose. Im 54 kg. My skin was 95 percent clear after month 1. I have been having bad flushing on my body and face so i stopped two weeks ago. However i don't feel i had enough because of the cumulative dose. Is there any way i can take 40 mg every two days until i reach at least 120 mg pet kg or will it not work that way?
