My daughter(19) was put on it for acne. It cleared up her spotty back like other similar pills wouldn't, BUT her moodswings are unbelievable. Even mid month she will have huge yelling fights with anyone, and seems to have lost her perception of the real situation, blaming everybody but herself, when it's clear to all of the family that any little trigger will set her off, crying and yelling! She won't change off it because the spots do come back ( we tried). We cant live with this moodiness, HELP!
