She was cool on here when she posted I'm sure she was great to hang with in person.

1. sex addiction is not a medical addiction, it is more along the lines of gambling addiction or generally speaking an obsession...
The "condition" shares nothing with medical addictions such as drinking/drug use. Some medical professionals calls the condition itself a hoax.
2. even if there was such a thing a sex addiction, penny was not addicted, sure she enjoyed sex and had perhaps a slightly higher than normal sex drive.
3. she eyed an opportunity to exit the game with some bravado, gotta give it to her, she is a very charismatic and communicative person.

did she light up a joint for Oprah?

You can debate what addiction is till the cows come home. Bottom line, it takes balls to get introspective and face your issues dead on, and then actually make changes in your life. Judging from her blog, the booze was the biggest issue, and the rest; the snorting, the smoking, the fucking all stemmed from that. So kudos for her for self improvement.

Whoot whoot! Penny!
