Hi,  I can't seem to keep anything down, not even water, everything I eat I throw up I've tried jello, soup, crackers and plain toast and I can't keep anything down at all it's really frustrating and I constantly feel very thirsty but throw up once I drink water. I have a doctors appointment Friday at 9, but I was wondering if you think I should go ahead and go see my doctor now I've already lost 6 pounds in less than a week from all the throwing up! Please help 😩
