This has gone on for years. If I don't eat first thing in the morning I get this really strong nauseous feeling. My mouth starts watering, and I have to do a breathing technique in order for it to go away. If I dont eat and instead drink a lot of water, sometimes I will throw up but it rarely ever has happened. And then my stomach makes a sound that I guess I would describe as carbonation. Like if you put your ear up to a can of soda. And after that the nausea is gone. Anybody else get this? I have been looking for an answer to this question and no one can help me understand what is happening.
