Iv a predisposition for depression for which I take medication. I'm worried that my depression will become worse. Recently I went to the heart doctor and he told me that my valves was getting rusty because of smoking. I can't tell you that I want to stop smoking but I know I have to and I want to intellectually. I don't think I can stop without trying the chantix but I've heard horror stories. My kids want me to stop smoking but they are afraid for me to take chantix . Recently I've been reading that chantix can damage your heart and since I've already started to have a problem I'm afraid it'll make it worse. Yet I think it's the only shot I have I don't know what's true about and what's not? The warning say something about depression and that scares me the most now it scares me about the heart problem. I'm undecided what to do
