I was wondering if taking 4 months of Accutane is too short as opposed to 5 months. I've been taking 80 mg a day since the beginning and I've reached the lower limit of 120 mg/kg a week ago. If I continue into the fifth month, I'll hit the upper limit. My skin is essentially with small pimples appearing now and then, and disappearing within a week, but the symptoms are starting to become quite pestering.

Would it be okay to stop my course early in the 5th month (not finishing 5) as long as I hit between 120-150 mg/kg total?
