My doc prescribed me to take 30mg Roccutane everyday. I do not want to take sucha high dosage. Any Suggestions?

SO... I have moderate acne and my doc recommended roccutane. I took it for 4 months 2 years ago and my skin cleared up completely. Am breaking out again and my doc recommended a second dosage of roccutane. I weigh 60 kilos and is 5'2. He recommended 30 mg divided in 2 dosages for 6 months. I was planning to start with 20 mg for 2 months and switch to 30mg for a month and then back to 20 mg for 2 months. I do not want to take such a high dosage for 6 months. Any suggestion would be appreciated.
