A Long Melford man sent his landlord a letter saying he was going to commit suicide, an inquest heard.
When police broke into Timothy Kidger’s home on Rodbridge Hill on December 3, his body was found on a sofa in the living room.
On Monday, an inquest at Suffolk Coroners’ Court in Ipswich heard that officers found a suicide note in which Mr Kidger, 61, said he had purchased a euthanasia drug from China using the internet.
The inquest heard that toxicology tests revealed the presence of a number of chemical agents within Mr Kidger’s body. Police had seized a tub containing a white powder from inside the house.
The cause of death had been given as a mixed drug overdose.
Assistant Suffolk coroner Dr Daniel Sharpstone said that Mr Kidger, who had worked for the mental health service before retiring, was suffering from Menieres disease but had declined to see his GP for help with the vertigo and tinnitus he was experiencing.
Mr Kidger had spoken of the condition, which was causing him to go deaf, as making him miserable, said Dr Sharpstone.
The inquest heard that, after police were alerted about the letter to Mr Kidger’s landlord, officers had to force open the front door after it could not be unlocked.
Dr Sharpstone recorded a conclusion that Mr Kidger took his own life.
