Realization
It was one particular day in Australia, where Clapton was cooped up in his hotel room all alone. He was alone with his thoughts, pain and misery. It was here that he realized he had to go back and seek treatment, not only for himself, but for Conor. He wanted to have a good relationship with his son, one where they could bond; not where he would be constantly thinking about when he could have his next drink.
Return To Hazelden
Although it had a sense of Deja vu in the sense of returning to battle his alcoholic demons, it was quite different in some ways this time around. Where he might have had some reservations about what brought him there the first time; this time he was more than aware. He had tried to control his drinking and ultimately failed. He needed help, and a major life change.
