I gave up years ago and never missed it.
The first few weeks are tough as your body feels like crap and you cough a lot and maybe eat/snack more, but it really is a case of being strong.
I'd simply remove myself from places where people smoke. So might mean not socialising as much. And of course, drinking and smoking for some go hand in hand, so by leaving the booze alone for a few weeks it might help. Also no smoking by anyone in your house. Ever again. They go outside or they don't smoke. Simple as that.
Wait till you can start smelling things properly and your clothes don't smell like an ashtray. Its bliss. And food improves in flavour also.
I just quit. No patches, no gum no nothing. Just woke up and didn't smoke that morning. Nor that afternoon, and into the evening.
If I didn't have that first ciggy of the day, which was usually closer to lunchtime anyways, then it was fine
Mind you I didn't smoke regularly. I'd go months between ciggys sometimes then smoke 15 in a day. I was more a take it or leave it type.
I also didn't make a fuss about it and tell everyone I was quitting. I just went on as normal and many people never even noticed.
If you are PG already and smoke I'd really stop asap as much of the damage done can occur in these early weeks. Its not just your health now, but that of your baby and there is that wanting to be around as baby grows up and able to play a part in their life, not watch from the sidelines or not be there at all.
I'd not want to inflict second hand smoke on my child either, so would not want to start again at any point in the future.
The negative health problems are well documented. There are no positives to smoking.
Plus there is the cost. The amount of times I've heard people complain and say they have no money for xxxxxx but yet they still go and buy 20 a day and smoke them all. It boggles
I must add that smoking now repulses me and I cannot bear to be around anyone who is smoking or to even walk downwind of someone in the street. I don't care if other people want to smoke, its their right and if its in a place where they are allowed to then fine, but don't expect me to vist a friends house if they sit and smoke in it or be happy someone stood next to me at the bus stop is puffing away. I'll move away so as to not have to be around it.
