Peter Lawrie has revealed his performances on the golf course suffered a huge dip because of an addiction to fizzy drinks.
The Irishman said he drank several litres of cola a day and battled mood swings when he tried to quit the habit in 2013.
Lawrie went from 161st in the world two years ago to 896th at the end of 2014.

The 40-year-old, pictured, said his addiction got so bad that he used to drink Coke on the golf course but going without it made him feel worse.
“I went from such a high on sugar to a dramatic low,” he told Newstalk. “I never recovered from it, I really didn’t. That was the one thing.
“I know this might shock people, but I lost all confidence in myself.
“I wouldn’t say I went for a breakdown, but I got exceptionally emotional at the end of that year and some of last year, as well.”
"It was just very difficult to deal with all of the situations that were coming at me. Whether that had anything to do with my mental state in any shape or form, I have no idea.”
Lawrie said he has fizzy drinks now, but in smaller quantities, and his form is improving. He has made the cut in his last three starts.
He said: “[Dropping Coke from my diet] just didn’t work.
"I don’t know whether it triggered something in my brain or whatever, but I wasn’t the same Peter Lawrie when I did it.”
