It is normal, in fact, if you get a stomach virus/food poisoning and don't throw up, that is abnormal because it's your body's way of
getting rid of
toxins. Honestly, I had a stomach
virus (BAD) the first week of February and I felt the same way, "oh man, I am throwing up so hard I'm going to die." But I just kept telling myself after that thought that "no, you won't die - it's normal, it sucks, but it's normal and I'm just going to open my mouth and let it come." Yuck.
