Rocker Slash was so hooked on painkillers during Velvet Revolver's tough recording sessions for their new album Libertad, he kept falling asleep in the studio.

While bandmates Duff McKagan and Matt Sorum were in rehab together and group tensions reached an all-time high following a difficult world tour, Slash tried to keep the supergroup together - but the pressure turned him onto drugs.
