Police stopped a man driving without headlights in the early hours of the morning and found he had been drinking.
Maris Subenieks (43), of Thistle Gardens, Spalding, had 67 microgrammes of alcohol in breath – almost double the legal limit of 35mcgs.
At Spalding magistrates court on Thursday, Subenieks was banned from driving for 18 months, fined £250 and ordered to pay £85 costs with a £25 victim surcharge.
The ban will be cut by five months if he completes a rehabilitation course.
He pleaded guilty to driving with excess alcohol.
Rebecca Ritson, prosecuting, said police spotted his Mitsubishi Carisma in Winsover Road at 2.15am on January 20 and used blue lights to stop it.
Solicitor Carrie Simson, mitigating, said Subenieks was on the way home from work when he spotted a friend, went to his flat and had a drink or two.
Subenieks then slept for about five hours and felt fine to drive when he woke.
He only intended to drive half-a-mile and would have walked that short distance if he had thought he was over the drink-drive limit.
Mrs Simson said Subenieks held a professional driving licence and hadn’t had an offence in 25 years.
