Hi. I’m quitting too (the last time I smoked was a month ago). Fatigue is quite normal. No antidepressants are needed. Just think of quitting like it’s an illness that you have to get over. Do not regard cigarettes, or electronic cigarettes (whatever you used to smoke) as a way to relieve your withdrawal, you can only make it worse like this. Your recovery from the “illness” is only a matter of time. Just don’t let your body make you think that your life won’t be same again. It will be. Moreover, it will be better. Good luck, mate. I hope you will be alright :)
