Anyone Out There Who's Has Had A Second Course/further Course Of Accutane

Okay so i just read a really discouraging blog about someone who has struggled with bad skin all their life and has tried everything , even accutane, but to no avail. two replies were off people who said that , basically, nothing could be done, that there is no 'cure' for acne. This SUCKS. is it true, really? ive heard that people who have been on a second course of accutane have a much higher success rate and much much less chance of acne returning again. I know it may be pointless as anyone clear probably wont use this site anymore....but does anyone know if accutane can clear for life? HAS anyone been cleared for life?? has anyone found after a second course this has been the case?!?!??!??! if it returns again i'll be so pissed....
