Seriously...where do I start??

so..like I said, I'm making changes. This morning for breakfast I had oatmeal and cantaloupe. I normally don't eat breakfast, remember hearing CP say that it is super important. was oatmeal a good combo with fruit?? There are so many conflicting weight loss tips I don't know which one to believe!! And much water, exactly am I supposed to drink? I've had 3 glasses today. Is that enough? And how about my turkey sandwich for lunch? I'm so freakin confused!
