I'm the same as majic... My boyfriend and I actually made an agreement that when I got pregnant, I would quit and he would not smoke in the house or around me. When the baby comes, he has to quit, too.
I will admit that i've had 2 cigarettes since finding out I was pregnant, but they were both after fights (on 2 different occasions) with my mom where I was so upset that I was hyperventilating.
It's really not been that hard for me, but I wasn't a heavy smoker to begin with. You can do it if you really want to.
