Is this the first time that you have quit smoking? Yes, it is a grieving progess...it has been your companion. Need to replace it with a hobby (or in my case, lots of sugarless chewing gum)
Personally I smoked for 15 years and come Novemeber I will celebrate 14 years smoke free.
I, too, loved to smoke and then one day I realized it controlled me and I did not control it. That was a big issue...I am not one to be controlled...it's give and take with my life.
I quit cold turkey...I smoked as many cigarettes as I could within a hour and was a bear to live with for 3 days...
Anyway by you quitting you are doing yourself a huge favor. Not only will your sense of smell & energy increase but your lungs will begin to rid itself of the black, tarry stuff.
Congrats...hang in there
