Welcome , I hope you decide to register. Most of us know how hard the addiction to nicotine is to break. It can be done! I am over 6 yrs nicotine free and boy it feels good. No more burned clothes, carpets, no more stinky smell, no more money down the drain, no more embarrassment if some one found out ( for many yrs many people I knew did not know I smoked) etc. It is not easy for a little "liar" up in your head keeps telling you that you need to smoke. Believe me it is not true. I tried Zyban and truly after a couple of weeks I forgot to smoke, before I got to my "quit" date. Even the patch is better for your lungs at least , it may help you with the habbit, but you still need to wean off the nicotine. You are young, if I added up your numbers correctly so it will be well worth it. Also some places have a 12 step program for nicotine addiction if you think a support group would help.
Just to add I also had a tumor found in my Right upper lobe, it touched to edge so I had chemo and radiation before they did surgery and chemo after. My lymph nodes were clean, and so far it has not shown its ugly head again, thank goodness. I pray you find a way. Good Luck Donna G
