Stomach pain and nausea will be the two easiest conditions for you to imitate and the hardest to confirm. Food poisoning often causes cramping and shooting stomach pain, so you might want to use these terms to describe your symptoms. Food poisoning often leads to dehydration and light-headedness. To convey these symptoms, you could say things like, "My mouth is really dry," and "Every time I stand up, I get dizzy." Food poisoning is often a highly unpleasant illness, so it's OK if you dramatically clutch at, hold, or hug your stomach and say you're in pain. Nausea can be indicated with a simple comment, like, "I've felt like I was going to throw up all morning." Avoid eating if you claim nausea, as most people can't eat on an upset stomach. Be careful not to overact too much, especially if you're younger and trying to convince your parents. Acting like you're in too much pain might end up with you getting taken to the doctor's office. If you have to convince parents you are ill and have enough time, you can make some fake vomit to convince them of your nausea. When you're sick, the last thing you want to do is make small talk over the phone. Keep your call short and to the point. Briefly tell the person to whom you are reporting sick what you ate, how you feel, and that you will not be able to come in to work or school today. You may want to change your voice a little bit during the call. Aim for a tone that is weak, strained, and/or sounds like you are in mild discomfort. Food poisoning often lingers, so it's best if you return to work looking like you're still feeling its effects. Try to avoid physical exertion and small talk. If someone asks you to do something physical, say that you're still feeling a little rough after getting over food poisoning and you cannot help.

Article: Many people need even more than the average of one-half gallon, per day. The individual amount needed depends on age, physical activity, physical condition, and time of year. Never ration water unless ordered to do so by authorities. Drink the amount you need today and try to find more for tomorrow. Under no circumstances should a person drink less than one quart (four cups) of water each day. You can minimize the amount of water your body needs by reducing activity and staying cool. Safe: melted ice cubes; water drained from the water heater (if the water heater has not been damaged); liquids from canned goods such as fruit or vegetable juices; water drained from pipes. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/c\/c5\/Manage-Food-and-Water-While-Taking-Shelter-in-Emergencies-Step-3Bullet1.jpg\/v4-459px-Manage-Food-and-Water-While-Taking-Shelter-in-Emergencies-Step-3Bullet1.jpg","bigUrl":"\/images\/thumb\/c\/c5\/Manage-Food-and-Water-While-Taking-Shelter-in-Emergencies-Step-3Bullet1.jpg\/aid355580-v4-728px-Manage-Food-and-Water-While-Taking-Shelter-in-Emergencies-Step-3Bullet1.jpg","smallWidth":460,"smallHeight":306,"bigWidth":"728","bigHeight":"485","licensing":"<div class="mw-parser-output"><p>License: <a rel="nofollow" class="external text" href="https:\/\/en.wikipedia.org\/wiki\/Fair_use">Fair Use<\/a> (screenshot)<br>
