Just to let you know, I'm on day 4 of the rest of my smoke-free life. I smoked for about 10 years, started when I was 15, as a lot of youngsters do.
But now I feel great. Yes, I am having a few cravings, but I'm keeping myself busy with anything I can think of. Doesn't matter how I feel though, it's all in my head and I will not go back to smoking. I'd rather hold my breath and pass out that put another one in my mouth.
Already I am noticing the changes. My head feels a lot clearer, physically and mentally. I can think straight and when I get up in the morning I don't have a terrible taste in my mouth. My hands always used to be cold, but now they are warm. I used to eat only once or twice a day, I'd replace food with cigarettes, but now I am eating a bit more and I can actually taste all the food properly, I am enjoying it, not just throwing it down to satisfy my hunger and provide more time for smoking.
I am actually less stressed than I thought I would be and I have a lot more money on me too, which leads to less stress. This has to be the best thing I have done.
Good luck to everyone else who is trying to quit. At least by actually trying you are taking the biggest step. Quitting is easy, making the decision to quit is the hardest part.
