I gave the nicotine cessation program my best shot. I have been totally smoke-free for five days. It has gotten worse, everyday. I was at the point in which I felt as if I were totally unable to function, so i put in a call to the prescriber, my primary care physician. I had called her office to ask how soon after taking off the nicotine patch is it safely allowable to smoke. I am awaiting a return phone call on either my cellphone or landline. It has been terrible.
