A self-employed businesswoman crashed off the road after one drink led to a few during a visit to friends.
Johanna Loughnane now faces having to put her home in Wargate Way, Gosberton, on the market and moving somewhere with better public transport so she can continue her work as an occupational health consultant.
Loughnane (49) was banned from driving for 18 months by Spalding magistrates on Thursday after admitting drink-driving.
She had 76 microgrammes of alcohol in 100 millilitres of breath. The limit is 35mcgs.
Rebecca Ritson, prosecuting, said police were called to reports of a car crash near to a roundabout on the B1356 at Gosberton just after midnight on July 13.
When officers arrived the driver was not at the scene, but a sandal was found nearby.
Loughnane was later tracked down, wearing a matching shoe, and taken to hospital for checks. A breath test was not taken until three hours after the crash.
Mike Conlon, defending, said on the way to the hospital Loughnane admitted to a police officer that she had been driving the car.
He told magistrates his client also helps care for her mother, who is registered blind, in Enfield and a ban will have an impact on that.
Magistrates fined her £200, ordered to pay £85 costs and £20 victim surcharge, She can knock four months off her ban if she completes a driver rehabilitation course.
