Keith Urban has admitted that his trip to rehab was much harder than he�d expected � well isn�t wasn�t going to be easy was it!

Urban left the treatment centre last week after three months of rehabilitation for alcohol addiction.

He wrote on his website: "Learning about abstinence was one thing, but then there was all this other area of my life to start learning about."

"And so 30 days became 60, and 60 days became 90, and with each week that passed I found myself really learning how to surrender."

Speaking about the time before he went in he added: "There was no big cataclysmic event that happened right before I went in."

"It was a lot of small things that were happening in my life, a lot of small moments that were starting to accumulate that were telling me very loud and clear that I was a long way from my program of recovery, and they were making my life unmanageable."

He also paid tribute to Nicole Kidman and said he was looking forward to getting back on the road.
