My goddaughter is going through the same thing. When she switched from nicotine to non-nicotine in the e-cig, she sort of went over the edge. E-cigs aren't the most healthy thing either, but she is powerfully addicted and needs some extra help to quit. She didn't taper off. She's starting over again and this time she'll taper off slowly so her body doesn't have to go cold turkey.

I've seen people who are super-addicted have great success with nicotine patches and gum. With the patches, it worked best if they started with the strongest, stayed on it for a month, then went to the second strongest. I think they come in three strengths. While they're going through the process of reducing the dose of nicotine, it also helps to work on the social cues and attitudes that cause relapse. It's not easy, but it's worth it.

If your doc says it's okay, the patches and/or gum might work for you. You can get some advice on the best way to do it from the cancer society.

Guide to Quitting Smoking

I quit smoking 12 times and failed. On the 13th try, I never looked back. I learned how to avoid the pitfalls that always got me started again.

Nicotine is probably the most addictive substance in the world. Some people respond greatly to it and quitting is harder for them. Please don't be down on yourself for having a hard time. Your particular biochemisty is probably making it extra difficult. It's physical. It's not character or strength or weakness. Your body chemistry just happens to respond extra powerfully to the effects of nicotine. The important thing is you're trying. It's very hard and it's worthy, not only for yourself, but for the sake of the baby.

I wish you the best of luck with this and hope that even if you stumble and fall a few times that you'll pick yourself back up again and keep up the good effort.
