"my doctor put me on this medication because i told him i get tired and moody throughout the day.. i had no plans to quit smoking cigarettes. i have been smoking for 5 years, 1/2 pack a day. after the 4th day, the cigarette kept on tasting worse and i couldn&#039;t even smoke a whole cigarette. hopefully i just quit, it&#039;s best for me and my health. the cravings for cigarettes aren&#039;t there anymore. on the 3rd day, i felt really weak and light at work. felt like i was going to throw up."
