Former Cheers star Shelley Long is back home after an alleged drug overdose, although her manager insists she merely took one pain pill too many to combat a severe back ache. The 55-year-old actress' spokesman Martin Mickelson has denied American newspaper reports that the star took an overdose after battling depression following the break-up of her 22-year marriage. The New York Post claimed Long was hospitalized on November 16. Mickelson insists she merely misjudged her pain medication and spent a night in hospital.
