BEVERLY HILLS, Calif.(AP) - In a three-year span Winona Ryder filled 37 prescriptions from 20 doctors under a half-dozen aliases, according to a probation report that concluded the actress is apparently addicted to pain killers. The report was released Friday after Ryder received a probationary sentence for stealing and vandalizing merchandise at a Saks Fifth Avenue store in December 2001. It paints a picture of the actress "doctor shopping" to obtain prescription medicines.
