OK..... i was going to post this too!!!!. I have just recently started smoking again. I stopped due to a whole heap of tests that I had to have done. I started smoking 4 nights ago and I have hit the joints pretty hard. I have noticed that I am getting REALLY sick now. Almost flu like symptoms and heartburn from hell. I Dont need to know what to do. I am going to stop smoking for a little while longer and work my way back up to being able to smoke as much as I want..... Has anyone else had this problem???? if so how long until you noticed that it was getting better and what else can cause the heart burn.... I dont really eat shitty foods Im quite ok with my diet..
