There is no magic pill, even with Chantix you have to stop it at some point and yes, you will have withdrawal and
anxiety, all the same things you would experience with a cold turkey quit....maybe a little less intense, I don't know for sure, but you will have to experience some so you better be determined to quit.
You have to take control back from the addiction. Be in charge and make sure you fight with everything you are. It is never easy but it is possible.
