"Long Island Lolita" Amy Fisher claims she was strung out on ecstasy the day she nearly killed her lover's wife, Mary Jo Buttafuoco, according to blockbuster TV interviews airing tonight.

Fisher, 31, now a married homemaker and mother of two, told "Entertainment Tonight" and "The Insider" that she was a teenage ecstasy and booze hound during her affair with Joey Buttafuoco - which led to her shooting Mary Jo on May 19, 1992.

"I was using ecstasy, a lot of ecstasy. It made me feel stronger and confident," Fisher told "The Insider."

"I was disconnected with myself . . . When you are using drugs, and I was partying, drinking with my friends, you don't remember. The reason I was doing these things was because I had unhappiness in my life."

Fisher claims she was high on the designer drug when she blasted Mary Jo on the doorstep of the Buttafuocos' Massapequa home - but clear-headed enough to recall details of the vicious attack.

"Yeah, and I remember she said I said certain things," according to Fisher, calling herself a "functional" ecstasy user. "I could drive, I could go to school. I had built up such a tolerance to it, I could function."

Fisher traced her descent into drug use to shortly after hooking up with Joey when she was still a minor, but insists the infamous auto mechanic didn't know about her drug habit. She said she concealed her ecstasy abuse, and typically got high in private.

"I was very quiet. I was using these drugs sitting in my room in a corner by myself, introverted," she said.

The love triangle took a brutal toll on all three players: Mary Jo's face was partially paralyzed from the point-blank attack, Joey spent four months in jail for statutory rape and Fisher lost seven years of her life behind bars for first-degree assault.

A cop who investigated the case said no evidence suggested that Fisher was under the influence when she pulled the trigger.

"There was none of that in the investigation at all," retired Nassau County Detective Dan Sererin told The Post.

"She never once claimed that at all in her statements to police and neither did any of the witnesses. It was never mentioned by any of her lawyers either."

The shooting drew national headlines and Fisher tried to hide her infamy after leaving prison.

A series of cosmetic surgeries and a switch to her middle name, Liz, instead of Amy, both failed to win anonymity for the convicted felon. The former bad girl conceded that no amount of superficial alterations would erase her horrible decisions.

"They [plastic surgeons] said a few subtle changes, it would change my face. It didn't," she said. "It's like psychologically, I was trying to . . . erase Amy Fisher."

She married Louis Bellera, the father of her children, Brett, 5, and Ava, 15 months, in 2003.
