Weight Loss Confusion

I simply do not understand it. I feel like I'm eating a lot! Internets, I do eat a lot. I eat every 2-3 hours (when I can swing it. Sometimes at school I go much longer. Hey, an 11-9 schedule doesn't leave much room for eatin', ya know?)

So how in hell's holy hand grenade am I still losing weight?! I dropped another half of a pound and am smack dab at 140. I am getting dangerously close to the 135 lbs I weighed when I got my drivers license, five freaking years ago. 

I thought I was going to gain weight, simply by eating immense amounts of chicken pot pie. Last night for dinner I had a half a grilled cheese (cheese = veggie slices) dipped in chicken rice soup. Two hours later I had a blueberry bagel with margarine. An hour later I had a slice of sourdough toast. Over the last week or so my appetite has come back--even when I take a bite of my delicious bagel I am dreaming of what I will eat in a few hours. Everything sounds delicious!

Granted, my meals are smaller than they used to be. (Thinks mournfully of my teenage years "snacks" after school--ramen, two bagels, maybe some cereal too, huge glass of orange juice, some cookies. [Not kidding in the slightest. I ate a lot]). I can't eat big meals now because it makes me reflux. 

Also, my cutting out dairy and eggs on the advice of my college's family practitioner probably has to do with the weight loss. I plan on discussing that with my doctor at my appointment on Wednesday. But I am still flabbergasted when I step on the scale and the numbers keep going down.
