In a quest to remain mentally sharp, Patrick Swayze turned away painkillers while enduring rigorous chemotherapy treatments during much of his battle with pancreatic cancer, his soon-to-be-released memoir, 'The Time of My Life,' will reveal. That, along with the actor's reaction and stoic acceptance of his disease, are just some of topics found in the book, according to excerpts highlighted by NBC's 'Today' and the NY Daily News. 'Life,' out Sept. 29, was co-written with wife Lisa Niemi.

Swayze died Monday evening in Los Angeles. Funeral plans have not been set, however fans will stage a memorial this weekend in the small North Carolina town where the actor's biggest film, 'Dirty Dancing' was filmed. Excerpts from 'The Time of My Life,' after the jump.
