Instead of assuming this quit will be like others you have tried, focus daily on changing your thinking to start looking at the positive things that have happened since you have quit. What things? Saved money, better taste and better sense of smell. You no longer smell like a stale ashtray to others. You no longer have to worry if you have enough smokes to last the day ...... There's all kinds of good things happening already in your "smoke free life"! Sure the early days are tough. You're changing the entire way you lived that daily life for years but you will not only get used to that, you will begin to love your new smoke free life more and more. The process is hard at first but it won't kill you. Going back to the smokes just might! You have the ability to focus your thoughts on whatever you want to ..... the challenges or the positives of quitting. Try the positive side. It will serve you better
