I'm very much addicted, physically and psychologically.
I also really do enjoy it; I enjoy snatching 5 minutes of me time 15 odd times a day. I really missed that time when I quit, as I use that time to reflect. It keeps me regular too 
When I quit I felt very isolated as I worried about nights out, lapsing etc. I was a lot more erratic in my thoughts; I missed the time out that smoking gives me. I was trying to explain how my days had changed since quitting and a friend summed it up very well, it was as if my days had lost their punctuation. That may not make sense! I also hated crying on the loo at random hours of the night desperately wishing I could just do a poo. Horrible! I put on weight too, and when I looked in the mirror I saw a chubby, miserable woman.
DS said seen first hand my many attempts to quit, and understands that I am trapped, and that to avoid being in my shoes he must never start smoking.
The worst thing about quitting? My temper. Anger just erupted from me with very little warning. I've worked too hard on my mental health, and I'm scared of rocking the boat right now.
It does scare me, I worry about the health implications.
