A row with his sister led a 40-year-old man to drink and then drive over the limit.
Artur Myszkowski, of Bridge End Road, Grantham, pleaded guilty to driving on Main Street, Great Gonerby.
Prosecutor Tracey Ross detailed how at 5.30am police pulled the defendant over in his Renault Laguna opposite Gonerby service station and Myszkowski failed a roadside breath test.
Jane Bauer, defending, related how the arrest occured when he was driving to work. The night before he had spoken with his sister over Skype, and they had argued over the care of their elderly mother.
Afterwards he drank whiskey and went to bed, believing when he woke at 5am he was within the legal alcohol limit.
Magistrates disqualfied Myszkowski from driving for 17 months, with the opportunity to reduce this by 17 weeks if he completes a drink driving rehabilitation course. In addition, he was fined £300 and must pay prosecution costs of £85 and a victim surcharge of £30.
