Quitting smoking was one of my most recent changes I made in my attempt to overcome my panic issues, that as well as diet and excercise ( body and mind )
I always wondered if smoking and panic had a relation, so I researched it. Nothing is concrete as their havn't been a lot of study on this, but the studies I have found do indicate a relation to panic/anxiety in smokers.
So in my attempt to work on my issues, I chose to quit smoking. At 25 days quit I notice a difference. I am much more calm and the short drives I have been making are better.
It doesn't happen over night, we need time to heal from the effects, you can't expect to quit and the next day all is well. I do think once you give your body and mind time to heal, not only will you benefit from quitting, but the way you think and perceive things will be better as well.
I was diirected to the Stop Smoking Center site from here. It is a wonderful support community. We can achieve our goals here and not be alone. It makes a huge difference.
