Hardest Thing in the World To Do

So today, I've finally decided to really do it. I've decided to quit smoking. Exams are over for this semester, so there is no real reason not to do it. I've been smoking for over 10 years now, and if I want to live forever like I plan..I need to stop doing things that are hazardous to my health. Plus, if I can successfully quit this time, certain friends of mine will not be able to bitch and kvetch at me about it anymore! LOL
So...I am now on Wellbutrin XL/Zyban..and I now have 21 days to successfully stop smoking, since that is how long I have medication for. I quit on it once before years ago for 6 months, so maybe I'll get lucky again, and actually be able to stop for good now! Here's hoping anyway!!
Wish me luck everyone! Life's going to be a bit hellish for me as I try to give up my addiction. I guess now I'll have to find something new to occupy my oral fixation...LOL As long as there is no weight gain, and my mood isn't too bitchy, I'll be able to get through this in one piece. I am viewing this as my Christmas gift to myself...better health.
