Actress Jodie Sweetin is finally telling the truth about her continued battle with drug addiction.

In her new tell-all book "unSweetined," the "Full House" actress she admits that she relapsed after claiming she had kicked her drug habit. She continued to book speaking gigs to make money to pay for her addiction.

"I was back to partying like I was at my worst, spending seven hundred dollars a week on meth [and] coke," she writes in the memoir. And she even admits to doing "key bumps" of coke right before speaking at Marquette University in Milwaukee, Wis.

From excerpts on The Huffington Post: "I talked about growing up on television and about how great my life was now that I was sober, and then mid-speech I started to cry. The crowd probably thought that the memories of hitting rock bottom were too much for me to handle ... They didn't think I was coming down from a two-day bender of coke, meth, and Ecstasy and they didn't think that I was lying to them with every sentence that came out of my mouth."

Wow, takes guts to fess up to something like that.

But how did she go from drug addict to sober mom to hypocritical drug addict?

She was sober when she gave birth to daughter Zoie in April 2008, but soon relapsed and split from husband Cody Herpin in November.

"The relapse started one day, just a few months after my GMA spot, when I got a random phone call from a friend who I used with and who occasionally sold me drugs. I invited her to my place. I was in an apartment at the time. I knew it was a really bad idea to invite her over but I wanted to test myself, I guess. We hung out, played cards. I told her I hadn't done meth in a while. One thing led to another and just like that, I was back," she writes.

"I was living a complete lie. But unfortunately, guilt doesn't make you stop. I talked about growing up on television and about how great my life was now that I was sober... The little bit of coke that I had done before the speech wasn't enough to make me forget how bad I felt for doing what I was doing. The guilt was eating away at me. I was struggling to keep it together, but no one realized that. I finished. They applauded. Standing ovation. Just how I liked it. And it was over."

Even after lying and crying in front of a room full of people, Sweetin admits to going back to her hotel room to take another hit.

"I was just so tired. Tired of lying. Tired of pretending to be someone that I wasn't. I took a deep breath and walked out of the lecture hall. I went back to my hotel room and buried my face in my hands. I couldn't keep doing this. It had to end.But not today. I wiped away the tears and finished the baggie of coke."

Maybe public humiliation and truth-telling will finally get her to kick her habit. We sure hope so for her daughter's sake.
