I started chantix 2 months ago. Stopped because I didn't have a repeat prescription. About 2 weeks in taking it I lost all energy that I had for about a week. I started it again 2 weeks ago and I'm the same as I was. No energy, weak, heartburn, sick to my stomach some times, feel like I could sleep forever. Didn't think about this til someone else said something to me. I just want to quit smoking for me and my family. Nobody understands how hard it is. It has taken my happy marriage and family. My body craves it. Please help. Is it going to get better?
