AUSTIN (September 27, 2012)--Texas Gov. Rick Perry denied Thursday he has sleep apnea after the diagnosis was revealed in a reporter's diary from a failed presidential campaign marred by several notable flubs.

Perry said Thursday he was misdiagnosed with the condition during the campaign.

Texas Tribune reporter Jay Root recently disclosed the diagnosis in the e-book “Oops!”

Perry's most notable misstep was his "Oops" comment during a televised debate when he couldn't recall which three federal agencies he wanted to eliminate.

Perry said Thursday doctors considered sleep apnea as a potential cause of his sleepless nights.

Perry tried sleeping with a special mask, but said it didn't work.

Perry had back surgery before the campaign and says now he was kept awake by a nerve issue in his foot.
