He was also found to have taken standard doses of the drugs diazepam, promethazine and citalopram, which had been prescribed by his doctor.
Coroner David Crerar found Mr Short had consumed alcohol to excess and taken his prescription drugs before putting a meal on the stove.
He then went to his bedroom and collapsed or fell onto his bed, where he died of a cardiac arrest.
Mr Short had a history of alcoholism, depression and suicide attempts, but Coroner Crerar found his death was not self-inflicted.
The coroner has warned against drinking heavily, particularly in conjunction with medicines, either prescribed or not.
