I quit smoking a month before being diagnosed and used the patches which did seem to help during the worst 2 weeks of withdrawls the stopped using them. Good luck to you and dont worry about the PEG it is a real lifesaver or at least it was for me, even with it i lost almost 40 lbs during and after treatment and after my apointment on AUg. 18th when i get the good news i am cancer free (just finished rad tx's at the end of may) I will get this tube taken out. I am now eating pretty well and have gained 5 lbs. My dentist recommended dentures so that made it hard for me to get used to eating again plus right now im in the middle of getting news ones that fit right so as of now i am eating without teeth. that first cheese burger i get when i get my teeth will be the best :-) . You have a long road ahead of you and were all here for you and to help in any way we can.
