Ashley Sibery, 39, was convicted at Edinburgh Sheriff Court last month of a culpable and reckless conduct charge for giving his wife Sital a fix of the class A drug in April.
The court heard how Sibery's wife had discovered her husband was a drug addict. She confronted the GP about his narcotic use and told him their marriage would be over if he didn't seek treatment for his habit. But Sital agreed to take what was supposed to be his last fix so she could experience what he felt when he took the lethal substance. She fell seriously unwell at their home in the Scottish capital and had to be taken to hospital.
