BOSTON -- A few weeks ago, NewsCenter 5 introduced you to four viewers who decided it was time to kick the habit and quit smoking.

NewsCenter 5's Heather Unruh reported that each was highly motivated and chose a different approach in their effort to quit smoking. Have they been successful?

"I didn't want to have any nicotine going into my body," former smoker Michele Berry said.

It's been eight weeks since Berry decided to end her 25-year smoking habit -- cold turkey. She got suggestions on how to quit from the Web. She even joined a gym to give her some extra energy.

"I did have a relapse about two and a half weeks ago. I wasn't eating properly. I was running around trying to get a part-time job," she said.

Since then, Berry has remained smoke free. She's certain she'll kick the habit permanently.

"I feel good about it. I'm 95 percent there," she said.

Juanita Upshaw used to smoke a pack a day until a good friend died of lung cancer. She joined a support group at Massachusetts General Hospital, and over a period of weeks, she gradually decreased her smoking. She said that the hardest part is that it's left her somewhat depressed.

"The withdrawal symptoms are really kind of like bad. If I'm around someone who smokes, it makes me really want a cigarette. So I really have to have good willpower," she said.

She's now down to a couple of puffs every three days.

"I can feel the bottom of my lungs now when I take a deep breath. I can feel the fresh air going in my lungs so it feels really great," Upshaw said.

Dan Berlin was a smoker for 10 years, until about 2 months ago when he decided to try the nicotine patch. He hasn't had a cigarette since. Now he's totally off of nicotine.

"It was actually over Thanksgiving this weekend. I was at my parents place and I forgot to put the patch on and decided not to wear it anymore," Berlin said.

He's even cutting down on the lollipops he used to keep his hands busy.

"I tried the patch once before, three years ago, and I had already failed by this point. Now I'm beyond that and think I'm definitely done," he said.

Eric Iby was skeptical, but the father of two had tried everything else to kick his 20-year habit. So, he turned to laser therapy? It was $300 for three treatments.

"Went into my session, came out, was incredibly relaxed. Went down to my car, didn't have any cigarettes in my car and didn't want one," he said.

In fact, after four weeks, Eric says his craving disappeared -- without the edginess he had with other attempts. He's telling everyone he knows about this new therapy.

"I've had my brother come in, his friend come in, my two sisters have appointments to come in. Just spreading the word," he said.

While they do admit it doesn't work for everyone, the Anne Penman laser therapy center in Burlington, Mass., said that most of their clients quit smoking.

All four of our subjects also noted the pressure of being on television did help them stick to their original goal.
