Virginia, you ARE doing a great job. You've already passed the physical addiction part, well most of it any way, and now are dealing with the mental aspect of the addiction. In just a couple days, you'll be through with Hell Week, and I'm sure you understand why exactly it's called that. It does get easier and easier as each day passes, of that I promise you.
Kerry, I'm sure your doctor can give you something to help with whatever you are having a problem with. But you need to understand that there is going to be some discomfort to put it mildly the first week especially. If you can make it through the first three days, you've made it through the better part of the physical addiction. Those are the days you have your very worst craves. If you hold out just a little longer and make it through your first week, things do start to ease up some. And then each day that passes after that just gets a little bit easier. You just have to sometimes tell yourself just for today I will not smoke, or this hour, or this minute, or somtimes even this second. But the more time, even as little as hours you put between yourself and that last cigarette, is that much more time towards the freedom you will feel once you get past the first really crappy days.
