A car veered off the road in front of Grantham Tennis Centre after the driver drank vodka and blacked out.
Police found the the Fiat with its wheels on the pavement and the driver smelled of alcohol.
Justine Morris, 42, of Hazelwood Drive, Gonerby Hill Foot, admitted being in charge of a vehicle while unfit through drink on July 9.
Prosecuting, Shelley Wilson said police were called to a road accident at 4.20pm where they found the front wheels of the car on the kerb.
Morris was the driver and was upset and distressed. She did not know where she was or how she got there.
She gave a positive breath test at the scene and a further test at the police station read 150 microgrammes in 100 millilitres of breath.
The legal limit is 35 microgrammes.
Kieran Patel, of the probation service, told the court that Morris worked shifts at Belton Woods Hotel.
He said she suffered panic attacks and after leaving for work she felt an attack coming on.
She stopped the cat and reached for a plastic bottle of what she thought was juice.
She drank the whole bottle which turned out to be vodka.
She did not recall anything after that because she blacked out.
Mr Patel told the court Morris worked shifts which did not help her panic attacks, for which she was on medication.
She had got herself a new job in Long Bennington, working nine to five. She was getting help from Addaction.
He said: “Coming into court has been a shock to her and she is very afraid of the outcome today.
“What she needs to do is to focus on her alcohol issues.”
Rachel Woodcock, defending, said Morris had turned left at the end of her road, when she should had gone right, and believed she had suffered a panic attack.
When Morris was at the police station, officers had to give her medication because she was so upset.
Miss Woodcock said Morris would find it difficult to get to her new job without a licence.
She said: “I would suggest this is a sentence in itself that she is here today.”
Magistrates disqualified Morris from driving for nine months and ordered her to pay £85 costs and a £60 victim surcharge.
They also imposed a six month community order with a stand-alone alcohol treatment order.
