Dear Wright,
It is quite a normal reaction to feel panic at the idea of never smoking again. Just imagine someone saying you cannot see your best friend ever again!
This is a similar feeling. After all, smoking has been so close to you for so long; it has been like your 'comfort blanket' when you were upset or angry or bored etc.
Unfortunately, we cannot sleep through the bad parts of our quit, but there are lots of things we can do.... some are mentioned in this thread, do the programme, and so on. Take one day at a time, as lemontwist says, stay on this site, and read and read as much as you can. Have some coping mechanisms ready for when a crave hits.
I went through this terror of never smoking again. I have not smoked for 9 years now, and it feels like forever but now, not in a bad way. You CAN do this, but don't try to do everything at once....just take your quit in bite sized portions, and it will all come together.
Whatever it takes, just don't smoke!!!
Love Lolly.
