Woodward was found by police in her £79,000 ($150,000) Mercedes G-class 4x4 at around 9am on November 17 near Alderley Edge, Cheshire.
The incident occurred two days after Woodward had attended the funeral of her husband - a lawyer who died following an undisclosed illness.
She had a sandwich, her dog and two unopened bottles of wine next to her. Test results at the police station showed she had 104 microgrammes of alcohol in 100 millilitres of breath, the legal limit is 35mg.
She told the hearing: "I buried my husband on Wednesday 15th November and the months leading up to it were terrible. He did everything, and then when he died I had to take over. I had never paid a bill in my life.
"I was just so distraught. I have never and will never drive after having a drink. I know it was wrong to have a drink in the car but I was desperate to get rid of the pain I was feeling."
The widower also asked that she not be handed an order of unpaid work claiming it would "put her in an alien surrounding" as she had never worked in her life and warned it would "make her feel uncomfortable and out of her depth."
Magistrates convicted her of driving with excess alcohol banned her from driving for two years - but spared her the unpaid work.
Woodward was also ordered to complete a 12 month community order, consisting of 15 rehabilitation days, was fined £560 and pay £705 in costs and surcharges.
