Do you recommend I stop smoking to get the most out of the protocol?
Yes, I definitely suggest you stop smoking to get the most out of my protocol. That should be your main focus. If you have chronic health issues and you are smoking, then, I don't really need to tell you this, but obviously that's not helping.
Pure nicotine isn’t a problem though. So you can keep taking nicotine. It’s tobacco smoke that’s the problem. So chew as much nicotine gum as you want, use a nicotine patch if you want. But definitely do whatever it takes to quit smoking cigarettes. Cigarette smoke inactivates B12 and also interferes with thyroid function.
