I had the same experience when I started smoking. It was horrible but I kept smoking. I eventually quit but I find it interesting that I ever continued. If I ate a food that gave me the same reaction I wouldn’t eat it again. Just saying… tobacco, alcohol, drugs…..all made me sick but it never stopped me. I would get sick in order to get the good feeling that would come later. With smoking I just wanted to be a cool kid with tobacco; with drugs and alcohol I just wanted to get high. Like my body was always screaming “Nooooooooo” and my mind was always saying “Bring it on! It will be awesome once you quit throwing up!”
