Snooki is giving up the alcohol!

No, the Jersey Shore star isn't headed for rehab, but…

She says she's put a hold on her signature boozing because of her expanding waistline.

"I haven't had a drink in about a week, so it's going pretty good," Snooki tells us. "I just want to feel healthy and obviously if I'm drinking, I'm not doing justice to my body. I just want to be healthy and get back to my ideal weight."

In addition to doing her best to find time to work out, she's also just signed on as a celeb face and body for the Dr. Siegal's Cookie Diet. "When I was in high school senior year, I was ripped up," said Snooki, 22. "I was a cheerleader and gymnast. I had the abs and I had the legs. I want to be back to 100 pounds. So I'm looking to shed 10 pounds."

Snooki, who is only 4'9", insists she has no plans to go under the knife for some insta-weight loss. "I'm not like 300 pounds, so I don't think I would need liposuction," she said. "I would never do any type of surgery like that."
