I don't have that problem in the morning, but it happens whenever I get worried. I hate it because I usually can't do anything to calm me down. It started my Junior year of highschool and at first I thought I had the flu. Luckily my dad noticed and took me to the doctor. It use to happen to his dad and himm and all his siblings. They gave me some meds to take if I know I am going to worry about something, but usually they don't even work. Some days if I have a test at school I end up throwing up in the bathroom for all of the class period. Usually I have to just wait it out. I wish you luck. I know it sucks, but you can make it through. I know a lot of the times it feels like you can't, but you can.
