You can handle it, artsoul. I'm so proud of how you've been doing in sobriety. It all comes from down inside. You found within yourself the courage and determination to fight for your very life. Quitting anything that we find comfort in (even if it is false comfort) is scary business. You have proven that you can do it regarding alcohol, and I have every faith that you can do it with cigarettes or anything else you truly set your mind to.
P.S. to add: Yes, I think you should go back to studying A Course in Miracles. I have the book but haven't really delved into it. My brother swears by it and even teaches a course in it. His life has done a 180 since he found it.
