Dear, sweet Jan was a coke-whore throughout her time on-set as well as a couple decades thereafter. (excuse the vulgarity, that's her own self-portrait and words).
Going on a Reality weight-loss shows made her hit rock-bottom and, with the help of Jesus, she turned her life around!
Odd book. She was a flighty hippy kid who was the meal-ticket for her dysfunctional family. Participated in all the silly and destructive crazies of the late 60s onward. While in one breath (and the written/spoken word) she takes responsibility for her bad behaviors, in the other she passively shunts the blame to others or puts it on the shoulders of the Situation.
The most distasteful aspect is her attribution of the bad behavior to her belief that she is manic and bipolar. (after years of multi-week coke-benders of course you are gonna be manic and bipolar -- too bad she hadn't read Keith's book). Apparently mental illness is a get-out-of-jail-free card in her case.
And, yes, she did chase after all her male costars; as well as any guy/gal in Hollywood & Europe with a little blow to share. The salacious tales of orgies, week-long hollywood hills drug parties, coyly phrased memories about european gay bars, forgotten marriages, and the like aren't all that novel and seem almost like a pathetic attempt to show some/any badge for years utterly lost/burnt.
A fun book. Like watching a train wreck. Her story isn't over, fer sure.
