minyan gal -I posted many times it’s a 3-pronged approach:
1. Addiction Therapy
2. Nicotine replacement (many ways -most common are patch and gum.
Try other ways if these two don’t work.)
3. Drugs -either Zyban or Chantix.
If you haven’t done these 3 things together, it isn’t called “trying”!
Also, you can try Chantix again on the lower dose, just increase the nicotine replacement -then slowly decrease.
