I quit with Chantix last year - I was amazed at how easy it was. However, I didn't put in the work to deal with my triggers to smoke and also quit the medication too quickly (primarily due to my insurance coverage, or lack thereof). I quit the medication after 2 weeks, lasted another 3 weeks before a major trigger and started smoking again. So, all in all I made it a bit over a month -smoke free.
I'll be using Chantix again for this quit - have already picked it up for my July 7th quit date. This time I'm doing the necessary work - PRE quit - to deal with the inevitable triggers AND I'm going to stay on the medication at least a full month then determine how 'ready' I am to deal with the triggers both cigarette and Chantix free...
Congrats on making the decision to quit - though you certainly do need to be making the decision totally for yourself, I certainly understand the influence the people in our lives have on us. Life is really about relationships after all.
YOU CAN DO IT!!!!
