I think you have shaken your head to many times
I understand where you are coming from! I have been a smoker since I was 17 and have only given it up once! It lasted about three months!
Let me know how that Psyctixs works for you! Someday I may have to re-approach the quitting, but I am hoping for one of those miracles where you walk in smoking and walk not even knowing you have ever smoked! The sad thing is that I smoke more playing DF, Yea I know, weird right! So I have no tale of successfully quitting or any nail butting tails of withdrawals of nicotine. The only thing I can say is that I should never have started! Yes, I should have listened to those that said don't ever start! Butt (get it, like cigarette butt), like you said Yem, you are invincible and the world will bow at your feat!
So I give you strength, courage and perseverance to overcome this! Utilize your problem solvers!!!
