Change of habits

Yesterday I decided that I was either going to be okay with not smoking, or I was going to go back to smoking again. I am tired of being caught in between and questioning my quit. I really thought about smoking again. Then I thought to myself...why would it be easier the next time I quit? And when would I get enough courage to quit again? Would life be less stressful at a different time?
So, I'm adjusting to life as an ex-smoker. I keep picturing how I will feel about this a year from now if A) I keep this quit or B) I go back to smoking.
I think the best way for me to feel great a year from now, is to keep this quit.
One my biggest concerns is the weight gain. I've gained 6lbs in 6 weeks. I have been better about the munching lately, but still continue to drink wine and eat foods high in fat. For some reason, fried foods are a comfort to me. The more fattening, the more comfort I feel. I need to change that.
These are the things I need to focus on:
- Getting enough sleep (when I'm tired, it's harder to stay strong)
- Drinking more water
- Eating 8 servings of fruits and veggies every day
- Exercise every day!
