"Celebrity Rehab' star  Jeff Conaway can't get off prescription drugs, wants to die at home, and have a Viking-style flaming boat burial at sea.

At least that's what his longtime girlfriend, Vikki Lizzi, says.

"This is just devastating," Lizzi told E!. "I tried to save him from himself by trying to get him help...He wants to die at home. He knows the meds are killing him. He can't get off them."
