Day 3 and I failed

I can't believe it but I broke down and smoked this morning. I have been 48 hours without any nicotine and just couldn't take it anymore. Now I feel like a failure and trapped in this endless spiral of smoking and hating it.Even though I am really down about it, I have tossed the pack and am starting over. So day 1,smoking cessation, hour 1 again. I am hoping that using this forum and hearing from people that have gone through it will make it possible. It is just so freaking hard to stop. Every cell in my body was screaming out for a cigarette,Herbal cigarettes, but I am determined not to fail this time.
