shake, shake, shake

I am so tired, I can't believe I am even going to try and post, but my nutrition has been so wacked out, I have to try and put into words a plan of action to fix it.
For example, today I had 3 protein shakes, and some mozzarella cheese with turkey pepperoni. Yeah, that's it. The day before I had 4 shakes, peanut M&Ms and some doritos. This is bad. However, I also did Zumba - which was awesome. The hubs and I have decided to join a gym together, one that has zumba type classes, plus all the equipment and child care. Not cheap, but essential.
It seems like since I made the decision to go back to school and pursue nutrition studies, I have been eating even worse. It would seem as though I would be making even more of an effort to work on my nutrition, but I think it's been a lot of emotional eating, so to speak. The shakes are a default. I can't decide what to eat - make a shake. I suppose it could be worse, but really - drinking my whole diet is not going to last long.
Anyway, I'm not sure of my plan yet. Everyday I wake up and tell myself I am going to eat normally, and 3 shakes later (Breakfast lunch and dinner) I try again.
Baby was up a ton last night - so, super tired. Big teaching day tomorrow. Gotta try and get some sleep.
