Margaret Parsons, 53, is pictured with cuts and lacerations to her face in a police mugshot taken after the incident.
She wounded the 61-year-old man – in what marks her third stabbing – in a vicious attack last December in St Austell, Cornwall.
Parsons previously served 16 months in 2014 for stabbing her then husband and a further three and a half years for knifing a woman in 2016.
The alcoholic was drunk during each incident and still on licence from a previous attack when she carried out her latest stabbing.
Parsons today admitted a wounding charge and was given 18 months in jail at Truro Crown Court.
Prosecuting, Ed Bailey said: “Shortly after midnight on Christmas Eve police attended her address after an emergency call made by her son.
“Two PCs found the defendant, her son and the victim there with the defendant standing in the kitchen staring down the corridor looking dazed. Her face, hands and hair were covered in blood.
“The victim was lying on the sofa and had sustained serious wounds to his hands and head.
“While there was provocation nothing could justify what you did”
Judge Simon Carr
“He was drifting in and out of consciousness, drowsy and confused. The defendant initially resisted being cuffed and tried to struggle free before being tasered.
“An ambulance arrived and the victim was taken to the Royal Cornwall Hospital, on the way officers noting a clump of the defendant’s hair in one of his hands.”
Parsons told police that she and her date went back to her son’s house on December 23 and started to argue about the music volume on the TV.
She claimed he put a knife to her face, bit her and pulled her hair.
Sentencing Parsons, Judge Simon Carr said: “There is no doubt you lost your temper and in the struggle that ensued you gained control of the knife and stabbed him a number of times.
“When taken by paramedics he had a clump of your hair in his hand.
“While there was provocation nothing could justify what you did and it is your previous convictions that make sentencing difficult.
“You were doing well with probation and had been released on licence.”
