In one way, shape or form or the other, it will last a long time, weeks, months years. BUT, that is exactly the reason not to surrender to the evil weed. While No Pain No Gain is true, there are many ways to deal with the quitting process.
It all depends on how long you have smoked, how many cigarettes a day (honestly), and how dependent you were. The biggest IF (and this is from experience of quitting several times), is do you really, really deep down inside want to quit. Or is it just something you think you need to do? This, I found, was the key. The last time (18 months back) I quit, my body and mind told me, enough, now it is time to quit. I have never looked back since.
Do you feel that way? If you do, you will succeed. I used a patch, but only as a stop gap measure to help me get thru the bad days.
Either way, good luck!!!
