Will i be able to function at work if not allowed to smoke?

I don't know you: I don't know whether you will be able to function, but it will sure be nice for everyone else! you can satisfy your nicotine craving (if not your psychological need for a cigarette) with nicotine supplements, either by using a daily patch or by using a short-term supplement (gum, nasal spray, e-cigarette) when you feel the urge. You can also consider the use of medical therapy, such as chantix.
