Hi, im a 27 year old female 5'8 about 135lb. I have no kids and am not pregnant. For a few months I have been getting very bad headaches after eating, or feeling tired and "drunk" immediately after eating. I have also experienced decreased attention and memory and have begun getting migraine headaches often times early in the morning and mid-afternoon (2-4ish). Often times my hands are shaky as well. Sometimes I feel nauseous when I am hungry. I sleep enough, eat a vegetarian diet (I get plenty of protein though). I was just hoping to get some advice on what it might possibly be or who specifically, I should go see based on the symptoms above. Thanks!
