The court heard Cheney wet himself in the front passenger seat of the police car, which meant it needed to be groomed by a professional cleaner.
Judge Michael Crosbie asked the defendant if he wanted to revise his estimate as to how much alcohol he consumed.
Cheney told him it may have been six or seven beers.
"Not that beer you get in Spain, that's got tequila in it, is it?" the judge asked.
"Somehow I think that is also a gross underestimate."
Cheney's explanation of his conduct to Probation was succinct.
"I f...ed up," he said.
The defendant explained how his children were living overseas and he would have "a few drinks" most nights.
Cheney confessed he would usually take a couple with him just to walk the dog.
The fact there was no injury or death attached to the defendant's driving conduct was down to good fortune, Judge Crosbie said.
"Essentially you're playing Russian roulette," he said.
Defence counsel Brendan Stephenson said Cheney had engaged with Alcoholics Anonymous since the June incident and his attitudes towards alcohol had changed.
His client claimed not to have had a drink since his arrest and Mr Stephenson argued a home detention sentence would be the appropriate outcome.
The judge disagreed.
"Enough's enough, Mr Cheney," he said.
The defendant was disqualified from driving for 28 days after which the alcohol-interlock protocols would apply.
