I think its time to Quit

I have been smoking for 7 years now. Ive tried to quit several times without success. I've wanted to quit but then something tells me that I'm not ready. Both my Partner and I smoked, until we were expecting my first, my Partners second child. My Partner went cold turkey, I wanted to quit then, but it didnt happen. My daughter is almost two and she see's me smoking or she knows when I go out the back that im going for a smoke and wants to come with me. I don't like smoking in front of my kids. The other day there was a butt laying on the ground in the backyard, my daughter picked it up and put it in her mouth like a smoker and said 'smoke'. This made my heart sink. Look at what Im turning my daughter into and she is only 2. I hate the fact that when I have a smoke I smell and I can't pick my daughter up as much as she wants me to, I hate it that when I want to go for a smoke and if she wants to come out the back with me I wont let her and it makes her cry. I hate it that I have no money to buy my family nice things. I dont want my kids growing up to smoke. I am determined to quit this time not only for my sake and for money but because that day my daughter had that butt in her mouth has made me feel so guilty and I'm to blame for that. Ive put on weight before when Ive tried to quit, thats part of the reason that I dont want too. This time is different. I dont care if I bacome fat, aslong as I quit so that I can play with my kids and teach them the right things in life. My step-daughter is always asking me to quit and telling me I stink when I've just had one. Thats it no more, I CAN DO IT. My quit date is 27 Feb 11, and im not going to touch a smoke after this date, not even half or even a drag.
