I will not encourage anyone to do anything outside of their Doctor's recommendation. My quit buddy went to the doctor this week for a check-up. He told her that the best success rate is for people to go the full 3 months and that it's not necessary to taper off.
I have another friend/colleague that quit taking Chantix after one month. She seems to be doing very well.
I'm just doing this for me. If I feel the urges are too much to get through, I'll go back on it. Simple as that. I don't believe I'll ever light up a cigarette again though. I've never made it this long and I feel so much healthier.
I could die from getting hit by a bus this afternoon. But if I am lucky enough to live for a while longer, I do not intend to be pulling an oxygen tank behind me. That is exactly where I was headed and it was too close for comfort.
