Way to go Farmgirl. We are all here to cheer you on. Any help you need, just ask. The first step is the biggest in wanting to change. I always say I'm on the Love Diet, cuz I'm in love and that's why I'm fluffy. Lol.
You bet anyone can do this and you are doing it. As you work out more and more, you will want to change your eating habits. But it's one step at a time. Good for you for giving up smoking. I quit in 1998 and never looked back.
Keep us posted please on here. So proud of you. Lets do this!
