I diet like a light switch

I'm always on and off. I will go for a while and then become unmotivated and stop then watch the scale rise and slowly start again. I've decided recently that I really need to get back into it. So i'm hoping to find lots of support and of course like a good sports bra I will give support in return. This is my first time on the site and looking to talk and meet people simliar to myself.
