It's been about 4 years for me since I quit. I went through about 10 days of not sleeping, night sweats, crazy dreams and all that good stuff. I've had a few hoots since quitting the daily smoking and it was never the same. I used to love the high...the escape.... but after clearing out and staying clean for months, it just made me paranoid. Now when I think about how great an escape would be, I just have to remember the feeling of wanting to hide in my closet till the high passed.
