Michael Phelps gives up drinking

After two DUI arrests, Olympic gold medalist Michael Phelps promises not to touch alcohol until after the 2016 Rio Olympics.

The 30-year-old swimmer has more Olympic gold medals than anyone in history, 18, and in an effort to add to his collection Phelps is determined to stay sober until next year's games in Brazil. He told the Associated Press he made the decision after his second DUI arrest in September 2014.

"Before I even went to court, I said to myself that I'm not going to drink until after Rio — if I ever drink again. That was a decision I made for myself," he said. "I have a year left in my career. If I really want it bad enough, I will make that sacrifice."

Following his 2014 arrest, Phelps was suspended from competing for sixth months and forbidden to participate in the world championships currently going on in Russia. He used the time to undergo a 45 day inpatient treatment, and enroll in alcoholics anonymous.

Phelps is currently competing in the national championships in Texas.
