It is a big adjustment but I've always loved that old saying of Jack Nicklaus: 'I retired from golf to go to work.' That sums it up for me.

You can't really describe how difficult it is to deal with. It is any athlete's worst nightmare to be accused of cheating by taking drugs. It really is very difficult to put into words how it makes you feel.

I'm happy in retirement.

I'm really looking forward to getting back and winning some matches but I'm not thinking about the U.S. Open yet, just getting through my first match.

The only way to get back the confidence is to play and win matches. You can practise as much as you like, but you need confidence that comes from playing and winning matches.

The downside isn't really injury, fear of injury or the process of fighting back from injury. The downside, the very worst thing in the world, is surgery.

My biggest problem will be lack of match toughness but I am a positive, optimistic person.
