I started this 1 time a day on May 10, then started 2 times a day on May 17, 2017. The side effects were horrible and have just now stopped as my body is now accustom to the medication. I stopped smoking on May 20th. I still have a desire to light up at times. So I think I just answered my own question. I shouldn't stop taking the medication until I no longer feel that desire. Or will I always feel that desire and will have to quench it for the rest of my life?
