Carnie Wilson's battle of the bulge has been an ongoing saga her entire life, but the 43-year-old singer hopes to finally slim down for good in 2012.

"I've had so much stress in the last year, so it's really a struggle," she tells FOX News. "I'm definitely up in weight. I'm looking forward to getting an exercise routine again. It's like a daily decision."

Wilson, who got sober in 2004, says her constant overeating stems from her inability to relax. "I can't smoke a joint. I can't have a glass of wine because I want 10 joints and 10 glasses of wine. That's my obsessive compulsive and addictive behavior," she reveals. "I've really struggled since I've become sober."

The Wilson Phillips singer and mother of two says she feels "very blessed in my life" but "at the end of the day I don't know how to unwind."

Wilson -- who lost a whopping 150 pounds via gastric bypass surgery in 1999 -- hasn't hidden her weight issues from daughters Lola, 6, and Luciana, 2.

"Lola knows I struggle with it. I see Lola loving sugar like all the other children, but I also see her pay a little more attention like when there's a birthday party. I see her being the first in line to get the cake. I see me in her," Wilson tells FOX News. "I think she's going to be all right as long as we're in control of this. She is an active child."
