He has maintained a disciplined routine for the past two weeks but if Andy Murray wins Wimbledon he will throw this out of the window and "celebrate hard".
Murray, 26, has put every effort into his match preparations to ensure he is in top shape for today's all-important tie.
Yesterday he vowed to "eat and drink all the right things" ahead of the clash and promised his diet would contain "nothing bad until after the match".
"If I did win on Sunday I'm sure I'd celebrate hard with the guys," he wrote in his BBC column.
But Murray, who is known for his love of sushi, said the Japanese delicacy "would definitely feature in there somewhere".
The British number one admitted he "treated" himself to a chocolate bar after the quarter-finals.
"But there won't be any other indulgences before the final, don't worry," he wrote.
"I'll eat and drink all the right things, nothing bad until after the match."
Yesterday the Scot took to the practise courts before returning home to spend some time with his girlfriend Kim Sears, 25, and his two dogs.
"I also had a bit of a snooze because I had a pretty late finish after my semi-final on Friday," he said.
