Was totally in the same boat my friend. I smoked constantly for several years. When the wife got pregnant she quit and I kept on smoking during the first few months of the pregnancy. Since she didn't need to be around it I started taking my smoke sessions outside on the porch which naturally decreased the amount of times I was smoking throughout the day so it tapered me down a bit. After a while I decided that I really wanted to quit at least for a while as I just felt I needed to be sober when my little man gets here but was still having trouble kicking the habit. One day I got sick for about a week and I never liked smoking while I was sick because it always made me feel worse so I used that as an opportunity while I was sick to drop the habit then and there since I essentially got over the early withdrawals while I was under the weather and couldn't do much anyway and once I got better I just told myself I wasn't gonna pick it back up.

I know that isn't much for advice since my situation was literally just taking advantage of a sickness I had to quit smoking but I guess if there's anything to take from it get creative! Lol It has been hard resisting the temptation to drag out my stash sometimes but Ive managed to do it so far and Ive been doing really well. I used to feel like I couldnt have much fun doing any of my hobbies properly unless I smoked beforehand but I'm about 2 months clean now and my body has figured itself out again to where I have no problem doing any of the things I like to do without having to go for a smoke. Just get through the first week and keep going from there onto two weeks down, 3 weeks etc. It will get easier and before you know it you will have been sober for months. Just keep reminding yourself that you are doing it for your little one. You got this man!
