I'm hungry!

I think I may need some sort of natural appetite suppressant. I almost always feel hungry unless I eat a lot of food. It's sad! I don't want to eat so much but I just don't feel full. I even try the 'drinking lots of water' trick. It helps a little but not enough. Are there any other tricks to curbing hunger? Maybe I should just eat carrots all day when I'm not eating a meal?
