It doesn't seem to matter when I wake up I seem to be sick most days when I wake up usually resulting in throwing up at least a couple of times. I have a healthy diet and exercise regimen and drink plenty of water and rarely smoke or drink alcohol. I have had a battery of tests including x-rays and Scopes of both the upper and lower gi. They have also checked my blood and urine and everything comes back normal. They tried giving me medication for stress and it didn't do anything. What do you think it could be?
