I have the same thing, but I have tested my blood glucose level. I tested my glucose for a couple weeks and found that it was always within the healthy range, but I definitely have more anxiety when I have an empty stomach. I get a sick stomach and sometimes it gets so bad that it actually becomes hard to eat. Anyway, I think it is anxiety because a little Xanax and the stomach problem disappears. I also have issues with stuff that is hot or greasy or rough on the stomach. I live in the South West where 90% of the food is hot, so I have stomach aches just from eating here a lot of times. Anyway, do you guys get sick to your stomach as well from lack of food? Does hot or spicy food affect you?
