Golf great Tiger Woods has checked himself out of a rehabilitation clinic he went to for help in managing his use of painkilling medication.

Woods was found asleep at the wheel of his car in Florida in May and was arrested for DUI (driving under the influence).

No alcohol was found in the 41-year-old’s system but according to police the American had “extremely slow and slurred speech” when arrested.

He later said he had an adverse reaction to medication, including Xanax.

“I recently completed an out of state private intensive program,” Woods posted on Twitter on Tuesday morning.

“I will continue to tackle this going forward with my doctors, family and friends.

“I am so very thankful for all of the support I’ve received.”

Woods released an apology after his arrest, in which he confirmed he was getting help.

“I’m currently receiving professional help to manage my medications and the ways that I deal with back pain and a sleep disorder,” he wrote on Twitter at the time.

“I want to thank everyone for the amazing outpouring of support and understanding, especially the fans and players on tour.”

Woods’ arrest came as he was recovering from a fourth bout of back surgery.

The 14-time major winner has been dogged by back problems in recent years, injuries that have seen him plummet down the official PGA Tour rankings.

Woods – who has won 79 times on the PGA Tour and was ranked the world’s top golfer for a record 683 weeks – has barely played in recent years.

He has competed in just 19 PGA Tour events since the end of 2013 and finished in the top 10 in just one of them.

Before the arrest, Woods wrote on his official website about how he was feeling positive.

“It has been just over a month since I underwent fusion surgery on my back and it is hard to express how much better I feel,” he wrote.

“It was instant nerve relief. I haven’t felt this good in years.”

Woods’ life infamously unravelled in 2009 when several allegations of infidelity led to the breakdown of his marriage.
