Hi Benjamin . My name is Dr . Green . What seems to be the matter ?   I've been feeling pretty ill for a few days now .   What are your symptoms ?   I feel chilly , I've got cramps , I keep throwing up , and I feel dizzy and tired .   It sounds like you might be a bit dehydrated . Do you feel thirsty most of the day ?   Yes . I can't seem to drink enough .   Have you been drinking plenty of water ?
