acne
"I first took this medicine in high school and was only on it for 2 months because the side effects were so bad.  Now, approx. 4 years later, I've now been on it for 4 months.  My side effects are much reduced.  I have experienced dry, peeling lips and dry eyes.  Suspension for 1-2 weeks allowed my lips to heal and I resumed the medication.  This occurred about 3 months in.  After 2 months, after much debate, I did get a tattoo which healed beautifully, quickly, and with no color degradation.  
I highly recommend this medicine only if you have consistently struggled with acne and no other medicine has worked.  Some side effects you just have to tolerate."
