Begining calorie tracker/plan

My plan is to shoot for 1600-1800 calories a day.  This is right in the range for 2 pounds a week weight loss and honestly I'm finding it difficult to hit 1800 while watching calories.  I have gotten a rude awakening to how terrible I have been eating for the last 15 years or so, as most of the main meals I eat are fairly healthy.  I've never drank a lot of soda or other bad for you drinks.  My downfall is sugar.  I have a serious sweet tooth and have a hard time saying no to cake, candy, cookies or anything else that comes out of an oven with sugar in it :(  I am determined to make this work however and as such am carefully tracking my calorie intake daily and will do my best to post what I've been taking in. 
11/29--2424 calories (obviously the first day I started tracking them)
           7 cups of water this day
11/30--1700 calories
          16 cups of water
12/1--1505 calories
          14 cups
12/2--1175+ (I forgot to track dinner so I'm missing around 400-500 for the day)
12/3-12/5--forgot to track at all :(
12/6--1330 calories
         4 cups of water today (not good )
12/7--1650 calories
         6 cups of water
12/8--1500 calories
         10 cups of water
12/9--1664 calories
         4 cups of water
12/10--900 calories (I must be missing a meal on here but not sure which)
         6 cups of water
12/11-12/13--forgot to track
12/14--1350 calories
         4 cups of water
12/15--1120 calories
         10 cups of water
12/16--1245 calories
          10 cups of water
12/17--1480 calories
         10 cups of water
12/18--1361 calories
          10 cups of water

So, over the past few weeks I have been below calorie budget essentially every day.  Now, it is obviously working as this morning I weighed myself and I am down to 316 which is an average of more than 2 pounds per week.  However, I do not want to send my body into starvation mode and 1400 calories is realistically too low for my weight so I need to add some calories to breakfast and lunch to try to be closer to 1600-1800.  I will try that this week and let you know how it goes. 

I also did a good chunk of exercise for me on the 18th.  It added to around 1 hour of walking and I noticed a large amount of energy in the morning after breakfast and half an hour of exercise.  I'll have to try to replicate this and see if that works consistantly.
