Louise Seatter got behind the wheel of her car just weeks after a previous ban for drink-driving expired.
The 31-year-old was stopped by police within yards of her flat in Aberdeen on December 17 and was charged with three driving offences.
Aberdeen Sheriff Court heard Seatter, an HR executive, had been "very unsteady on her feet" when police stopped the car. The lowest of two breath tests given later revealed she had 178 microgrammes of alcohol in 100 millilitres of breath.
Defence lawyer Peter Keene told the court Seatter had decided to drive to get away from a creepy internet date.
He said: "My client had arranged to meet a person that she had been acquainted with through an internet dating site. She intended to drive there and have a taxi bring her home.
"She became increasingly concerned regarding her companion and he turned out to be very creepy and she panicked about that.
"She felt that she was in some sort of danger, she got into her car and drove the short way home."
Sheriff Marysia Lewis said she could not recall having dealt with such a high breathalyser reading before. She deferred sentence until later this month.
