Well what do you eat in a typical day? Write everything you eat and drink, and maybe we can give suggestions. One suggestion is that instead of drinking water when you're thirsty, try to always drink something with calories...something really good is Chocolate Silk soy milk, sooo yummy! Also try eating dessert breads for snacks like zucchini bread or banana bread. What types of foods are easier for you to handle? Can you handle peanut butter?
