A 41-16 victory in Sydney on Saturday saw the Lions triumph on tour for the first time since 1997.
Despite being controversially dropped for the final Test, O'Driscoll insists that he is happy with the outcome.
"Obviously I'm delighted," the Irishman told Sky Sports News. "It's been a roller coaster week. It was emotional sitting there. We've won the series and any of the negatives felt through the tour will be forgotten. It feels good."
The last time that the Lions were successful on tour was in South Africa 16 years ago.
