I still have dreams that I light one up, just to see what will happen, and I end up hooked again.
I get those as well, even though it must be 8 or 9 years since I quit. I wonder how common it is.
Can't comment on what smoking does to blood sugar, but there is actually sugar in the filter - I read it on the internet, so it must be true.
@hisjen84 If it helps, I never really managed to quit by deciding "that's it, I quit!". What I told myself was " I don't really fancy one right now", resisted the odd one, and spent less time in situations where I would smoke just out of habit. After a while, it was longer and longer since I'd last had one, and only after some time did I really think of myself as an ex-smoker and stop carrying baccy and a lighter everywhere.
That was the thing for me - it wasn't 'I don't NEED a smoke' (will power), it was 'I don't want one just now' (a choice, even though I knew I was telling myself a fib just to change my mindset).
Hopefully I don't sound like a preachy ex-smoker. I know at the time I found myself getting a bit 'holier than thou' a few times and suddenly had to bite my tongue.
