I'm so damn hungry

This summer I'm enrolled in a Yoga/Health Class for my kinesiology credit. As part of the class I had to calculate my ideal weight and caloric intake and keep a food diary showing an effort to be healthy. I am supposed to consume somewhere between 1400 and 1500 calories a day.I think it is killing me- I'm so damn hungry that all I can think about is food.Right now, for instance, I am pondering a hamburger with cheese and bacon. Yesterday I could not stop thinking of quesadillas. Plus, I'm trying to drink the recommended amount of water per day. Do you know that if you drink all the water you are supposed to in a day you will gain a new hobby? You will. It is called peeing like a racehorse every hour. So far today I have had three and a half glasses and I have gone to the bathroom six times since I got up at 6:45. I do not have time for this many calls from nature. It would be different if the water were helping with the hunger but it is not. Can I seriously fail a class for refusing to give up calories? Argh!
