Since I have had alot of pulmonary function problems lately, I am gonna try to quit or majorly cut back smoking cigarettes. I got my doc to write me a script for Chantix. Has anyone out there tried it? I have tried the patch & the gum before with no help at all. Doc said Chantix has a 40% success rate over a 3 month period. That didnt sound very good to me. But, she said that is huge. I am also gonna take a 4 night class that is spread out over a month. Hopefully this works. I really enjoy smoking though. If I am drinking alcohol or after a big meal, i always smoke. Smoking is also a big source of stress management for me. This is going to be a very difficult thing, but I have to at least give it a real try. I smoke about a pack a day, give or take. Most of my friends smoke too, so I will be around it alot. I have had several docs warn me that if I ever try to quit smoking, I need to do it slowly or it will cause the RSD to flare really bad. I am starting Chantix tonight, but doc says I have to take it for a week before I start backing off, not sure why. Wish me luck!!
