Welcome golfmom01, You sound exactly like I did 5 months ago! First of all the apprehension is normal. You are deciding to give up something that has been your constant companion for about 35 years! What will you do?! You will live longer and you will feel better. It is time to ditch the demon! Some days will be easy, some not so easy but doable. If you really want to quit nicotine for good aided by the Chantix you can. Read thru my past posts and alot of other sucess stories here and you will see. Follow the instructions especially about eating and drinking with the med and you will see how it works over the course of the first 7 days. It works differently for everyone and my experience was wonderful. I smoked as long as you did, 1-2 packs a day. I have been smoke free for 5 months and 4 days and have been off the Chantix since May 6th. I had surgery also and was able to quit prior to it and healing was alot faster. Familiarize youself with nicotine withdrawal symtoms so you know what to expect and not freak out. Some experience withdrawal worse than others. I cut way down on the cigs before my quit day and feel withdrawal was not as severe for me. I could go on and on but I will wait until you start the med so you get a feel for it and then just answer questions you have. I hope you have a successful quit and pleasant experience with Chantix. I will be cheering for you! You are going to love being a non smoker!!
