"after i had been on this medicine for 6 months (only 20mg as i am quite petite) i was still breaking out, frustrated and over having cracked lips and dry skin i asked him to up my dosage. he did not want to due to my weight but agreed to let me take 40mg every second day. he told me i had to stay on it up to 8 months! i was devastated! after another month i had some improvement but still breaking out. i gave up as it was coming into summer and i live in a very warm, beach side place and stopped taking it. after about 3 weeks my skin was clear! i have been off it for about 4 months and my skin is 100x better! i get a tiny pimple once in a blue moon but that&#039;s it. guess it&#039;s different for everyone but my best results came after i finished!"
