Banjo, just give up. I found it a lot easier than expected. Before I fell regnant I was a serial quitter, every Monday I would stop, then the following Monday I would stop again because I had started again on the Tuesday, etc etc.
From the moment I found out I was pregnant I stopped and haven't had one since; just think of the little one, it's tough enough for them already without increased risk of miscarrriage or respiratory disease like ashtma once they are born - it;s not their fault, and it will do you the world of good.
