I am sorry you are going through this as I too have lung problems and yes, am a smoker too, although a lot of the times I will just hold the cigarette, just holding it makes it easier than just "throwing them away"

I am like you in the fact I eat well, I exersize {well I did until recent setbacks won't allow for it} and I don't drink. So smoking was my only vice, I still have to take a drag now and then or I would lose my mind. I don't take Pred {due to allergy} but I can say pred makes you a bit "crazy" or it did me

I am putting a post up about another lung issue you might want to look into.

And for all you other smokers, here is something to ponder.

My brother-in-law was a heavy drinker and smoker, when he was DXed with cancer he quit smoking and drinking and he got soooo sick that we all told him to stop quitting, that the stress on his body would kill him faster. I know I shouldn't say that but its the truth.
