I did it and I was a chain smoker line no other! I'm 48, was told if I didn't then I would not make it. I started using a vape, first with nicotine and now with zero nicotine so it's basically flavored air. I am 90% better and I couldn't walk to the car without feeling like I was drowning! Praise the Lord! It's the hand to mouth habit you have to find replacement for. Chantix also makes you just not want to do it anymore but some ppl suffer from depression after taking it. I thank God Above right now for taking that urge and desire to smoke out of your mind! I rebuke the spirit of addiction in Jesus' name and command it to leave their body and NEVER return! Thank you God for your grace, your mercy, and your love! In Jesus' name I pray and call it into reality from the unseen! Amen-SO BE IT!
