I started getting sick in spring of 2005. I quit smoking in 11/06. (I had many failed attempts previously.) It took me 4 months to finally quit and I only smoked 2-5 cigs/day. I am STILL craving cigarettes and think about smoking. These suckers are sooo addictive!
I've thought about starting smoking again to help my endless flares. But, I haven't started again. My reasons not to smoke are better than my reasons to smoke. First, my kids won't understand that I'm smoking to help my UC. They'll only see that I'm smoking and think that it's ok to smoke. Then, I think about how awful the stink is and the effects on my lungs, yellowing teeth, wrinkles, etc.
It took me 3 years to get my UC under control. I've been in remission 3 times; my longest remission was 2 months and I just started flaring again. Still, for me the negs of cigs outweigh the plusses.
Smoking is an individual decision. I hope that you make your choice not out of desperation, but with a clear head. I just wonder whether cigarettes are like so many other things that we hope will help our UC but don't. Then, you're back addicted and still flaring. That would s7ck.
