Battling Nausea

Today I have been the most nauseous I have ever been. Many people have told me to eat small meals every 2 hours but I can't even handle that! I am constantly nauseous and extremely tired and eating is the last thing I want to do. I will choke down some crackers just to settle my stomach as much as I can but that's about it. Then after going practically all day without eating I am starving and a "small meal" just isn't enough so I eat until I am full. Ugh! I really hope this ends in the 2nd trimester! Also nothing ever sounds good so I have been breaking the bank buying food that I am craving because the food I thought sounded good when I bought it no longer sounds good. :( The only good thing about this is that I am maintaining my weight because I don't want to gain too much since I am already overweight as that will be dangerous for myself and the baby.
