After getting a DUI in 2014, Michael Phelps said he was "in a really dark place" but has since made a change for the better.

The Olympic swimmer spoke to Sports Illustrated and gave an insight into his alcohol problem and what he was going through at the time.

"Honestly, I thought, the way he was going, he was going to kill himself," Phelps' coach Bob Bowman said. "Not take his own life, but something like the DUI, but worse."

After the conviction, Phelps was convinced to enter a rehab in Arizona. He spent a total of 45 days there and now claims that he has changed.

The Swimmer sounds positive about the future, saying that he has given up booze at least until the 2016 Olympics in Rio. "Haven't had a single sip and will not have a sip. My body fat has dropped significantly, and I'm leaner than I've ever been." Phelps said.
