Man, do I know where you are comming from! I am on day 3 here. Sort of started in the 21st, but was still smoking on and off. This past monday I said that is it. I have tried it all too. The diference this time? I don't know really, I am just ready. I WANT to quit. Yea I feel like I NEED a smoke but I keep telling my self I don't want one. It's hard, REALLY hard, but the mind is a powerful thing and it's a lot of will power and mental determination. Always think about why you are doing this. Oh and Yelling, having a fit and just going a little batty help. Just DON't Light up and, do it when no one is around. You'll either get someone upset unintentionally, or they will think you have truely lost it. find a way to release that anxiety of not having a smoke.
Keep telling youself you are strong and you deserve more than a cig can give. YOU ARE IN CONTROL not USA GOLD ULTRA LIGHT 100'S (that's what I smoked)
