Congratulations alsaser...
Hang in there, the first week or so is the most difficult. You can do this! I quit many times before this final quit, at least 10 times. Took classes, over and over, did gum, patches, cold turkey... everything, but it never lasted forever. (2 times I went a whole year!) This time I was DETERMINED to NEVER smoke again! That's the key,...the main ingredient- - -YOU HAVE TO BE DETERMINED!!! Those other quits, I didn't do it with my whole heart. Half hearted attempts, and I was always thinking in the very back of my mind...'someday I'll get to smoke again'.
I hope you have this determination...100% resolved to quit, no matter how tough it gets.
It does get easier as time goes on.
Best of luck, and let us know how you are doing.
