The Coldplay singer admitted that he has kept up the unusual practice for the past decade and believes it is an effective way of avoiding further mistakes.
"It started when I had to ask forgiveness for sacking our drummer Will Champion ten years ago," Martin is quoted by the Daily Express as saying.
"Three days later the rest of us were feeling miserable and we asked Will to meet me and our bassist Guy Berryman in Monkey Chews in Camden where we asked him to come back.
"They made me have lots of vodka and cranberry juice in remembrance of what a nasty piece of work I was being. Now if I find myself making a big mistake I have to force myself to drink that stuff to remind me not to be such an idiot!"
Martin was described as "insufferable" by comedienne Katy Brand last week.
