The actor--who played Kenickie in the iconic 1978 musical movie--was struggling with severe cocaine, painkiller and alcohol addictions when he signed up to appear with other fallen stars on psychologist Dr. Drew Pinsky's TV experiment.
He quit the program early when the facility that housed himself and others, like fellow actor Daniel Baldwin, reportedly ran out of the pain medication he needed.
But Conaway isn't opposed to returning to Celebrity Rehab for a planned second season.
He says, "It's not over, I'm gonna go back in."
Conaway insists the recent death of his mother made him realize how far he has come: "I miss her a lot, but I didn't go back to using over that."
The fallen star admits he still needs to work on his painkiller addiction--and that's why he'd like to return to Celebrity Rehab.
