Biggest Struggle.... portion control

I am working on conquering my biggest issue which is eating way to much. I'm struggling with it, but last night I went to store and got myself all sorts of veggies to eat while I am work. I think this will help a lot. I am excising a lot but I am not seeing the weight loss because my eating habits haven't changed. I am somewhat disappointed in myself, but I hope to use this as a lesson to learn. I wasn't to lose a good amount of weight before my trip and well it didn't happen. So now I have to learn from my mistake and keep moving forward. I hope that this is motivation enough to really start making changes.
