Should I try accutane?

I have mild-moderate acne, and I'm sick of worrying about my skin. I have tried everything I could think of (diets, birth control, every skincare regimen under the sun, natural remedies, ect.). My cousin (whos acne was far worse than mine) benefitted from accutane and suggested it to me when I told her how I felt about my skin. Should I try accutane? What are the most common side effects?
