So I started yesterday and it was going fine until later in the evening. I started with a headache, and then it felt like a sinus headache. I soon got very hungry but very sick feeling at the same time. I was starting to get dizzy and shaky. I work during the day and go to school at night, and I actually had to leave class. I went to the hospital but it was so busy that I just left. I stopped by the store and bought some soup because I was really craving it, and was feeling even more dizzy. As soon as I got home I threw up. I rested for a few minutes and had some soup and felt better after that except for a small headache. This morning my husband took me out to breakfast and I had some potatoes and a bagel. I called off of work because I was still feeling weak and a little shaky, even after a big breakfast. It's about 2pm now, and I'm still weak. I'm having some cranberry juice and an apple, don't feel like eating much. What is going on and how can I fix it?
