Everyone is different. The physical urge should be gone in a week. The mental urge can last for a long time I am at 5mo and there are still little things that trigger an urge a smell or an action. I have tried to rewire my urge buttons not letting things get to me to make me want to smoke. One thing I did a bit in the 1st month is stand next to someone smoking and get in some second hand smoke by the 3rd mo I could not stand the smell of a smokers clothes.
An urge only lasts a moment and should pass. Remeber why you quit! Try having a drink of water to satisfiy the urge you need the water any ways to flush your system. A mint toothpick may work...Just remember find a health habit to replace the smoking. I munch sunflower seeds and now have to ween off them.....Exercise will help your mental health walk a brisk mile. The meds should help you if not after 6-8 weeks talk to your Dr and try another one.
