A big, fat brick wall

So I joined Planet Fitness back in June and I try to go at least 2x a week (but missed 2 weeks with a foot injury). My husband has signed up and is going with me. He's gone twice and has lost weight. I've been going for the whole summer and I keep fluctuating right around the same 3 pounds. I lose them, I gain them, I lose them, I gain them. It's really frustrating and I need to figure out my food issues and replace them with something healthier. My first small step is going to be to replace most of the coke and mt dew I drink with water. Oh.. And the McDonalds Sweet Tea. I don't know if I have the self control for that....

I started a reward system for my weight loss plan. After I lose 15 pounds, I'm going to get a manicure and then 25 gets me highlights and 35 a haircut. Ive never had my hair cut before. My mom has trimmed it and shortened it, but I've never had a style. I'm starting to feel like I'll never get there.
