hi farrah,
maybe this will help motivate you. June, my sister-in-law, has just been placed on a list for dual lung transplant. she is in her early 60's, a long time smoker. June has Pulmonary Fibrosis, which is not caused by smoking. she is on oxygen and mostly uses a wheelchair. when she walks, her finger nails turn blue from lack of oxygen. the blood level gets down to 50%.
3000 folks per year need lungs in the US. 1000 get them.
i didn't know that lung transplants were possible and think it is almost magic that docs can do that. June is lucky in that she still has treatment options... i don't know if lung transplants are available for cancer folks. no one that i've known with lung cancer has been offered a transplant.
i think it's great that you are trying to quit smoking and wish you my best wishes. i know it is a very difficult thing to do. be strong and do your best.
cu,
larryb
