I quit cigarettes and now I can't focus in Office!

Cigerette is disgusting. And this is coming from a former addict. The hit only lasts few minutes or hours and then you crave it again. Imagine how it makes you feel after, it makes you smell bad, you cough, you feel out of breath just after walking a little. It surpresses your hunger. There's a book called "Easy way to quit smoking illustrated" . When I had read the book for the first time I quit it for long even though I had no intention of quitting at that moment. I threw out my ash trays and lighters. The whole idea of that book is that you can keep smoking it while you're reading the book. And only quit when you feel like it, give it a try what's there to lose
