I have been taking Chantix for a long time. Nausea was horrible for me. I asked my doctor for anti-nausea medication and it really helped when I needed it. But now it is rare that I get nauseated. Keep taking the Chantix. It may take a long time but your nausea will end. Your body will eventually adjust. It's a miracle drug. It stops the cravings. Chantix blocks the nicotine receptors in your brain. What that means is that when you smoke you don't get the nicotine fix like you did before. AND -- this is the best part -- it stops the cravings. Somehow it keeps you from wanting OR NEEDING another cigarette. You'll say, "eh...nah, i don't want one". The desire goes away and soon you won't be craving one or dreaming of smoking. I don't know how it works but it does. It'll get to the point that when you convince yourself to have one you be thinking why, since you don't get a nicotine buzz anymore, and you'll just smell up your clothes. Just so you'd know, I tried all of the nicotine patches, nicotine gum, prescription inhaler, prescription drugs, hypnosis, cold turkey, you name it. Chantix is the only one that worked for me. It will work for you too.
