I don't know if they have changed it since then, but I took it for 3 or 4 months, and the worst part was the cracked lips and dry skin. But I don't regret taking it at all. You didn't say if you are male or female, but if you are a woman, you must make sure you use reliable birth control, because it can cause birth defects."
