i have watched my dp try and give up smoking many times and i can see its no easy feat... try not to feel guilty because one cigarette is better then more then one.. do your best and reward yourself for the small steps you make towards your goal.. just remind yourself that you are trying your very best to do whats best for your baby and don't get down on yourself when u slip up because its going to make u depressed and make it harder.. i know i am not in the same boat and i can't fully understand but i am here if u needa vent andi hope my post has been somewhat helpful rather than just preg brain babble
