The only thing that worked for me was as soon as the desire to smoke hit me, I put my mind on something else. The desire to smoke goes away if you smoke, and if you don't. Will power will not do it. Don't think of it as "giving up smoking" think of it as stopping.
If that doesn't work, think of me; 47 years of smoking and all I got from it was CANCER! You are a singer, now, imagine what it must be like to be totally unable to sing, and worse yet, unable to talk. Now, light another one, Luv.
