Hello all, I've been a smoker for 25,years. And I've been on the chantix month start pack and now down to my last pill. I'm doing good but feel like I need another week or so on chanix to feel I 100% done! I don't know if its in my head or should I call my doctor to get a refill? Ive came so far now hardly smoke but not completely done. I don't want to fail. Previously starting. I took a week and felt nausea and had surgery to so I stop taking a week or so but got right back on it. That's why I think I'm feeling I need another week on it and will be out today. Any advice I so will appreciate it, thank you.
