Starting my 4th week of being smoke free. Some days are more agonizing than others but I feel that I am about to turn a corner. Since I quit smoking my coffee consumption has decreased and that is probably a good thing. I take an occasional Niacin tablet as it is suppose to be helpful in fighting cravings. I am not sure if this is effective or not but I am sure that it is not harming me. I really need to drink more water. It will flush out the poisons.
