The former Australia leg-spinner's marriage to then-wife Simone had reached a low point and Warne revealed he would drink heavily before crying himself to sleep in the team hotel.
Warne, who was in London this week promoting his new book 'Shane Warne's Century', told the Australian Daily Telegraph: "At night I'd lay there and go 's**t, when am I going to see my kids?'
"There were times I'd sit there and drink in my mini bar until three in the morning just to get to sleep, set the alarm, wake up and say: 'here we go again'.
"I cried a fair bit when I was by myself. I'd say to myself 'You d***head, what are you doing? What have you done?'"
