I quit almost four years ago. It is very, very hard but ABSOLUTELY worth it. It is nice not to sneak around finding a place where it is okay to smoke....breathing deeply...enduring long plane flights without fits of withdrawal.... lots and lots of good things...

Now I go for days without even thinking about a cigarette and I cannot picture myself again.

Keep it up! It will be worth it!

p.s. yes...emotionalism and insomnia are part of withdrawal!
