So today was supposed to be day 5 for me of not smoking and for some reason I just gave in to the craving. I have been feeling sick all week and my skin feels like it's crawling. I had a cigarette and the sick feeling instantly went away. So now I know that me feeling sick as a dog was actually me going through nicotine withdrawl and the thought that I will have to go through that all over again makes me nervous. I just hope that I can be strong enough to not let the cravings and withdrawl get to me.
