What should I eat when I feeling like puking/throwing up... ?

first im a 13 year old boy** im really sick have had a headache/stomache for the past 2 days and 2 nights .. this is my thrid day! .. anyway yesterday almost all day i was cold .. because i went out in the sun for an 1 hour with my sweater on and long sleeve shirt on underneath and i was out in the sun the whole tim! (yes i was wearing sunscreen) and i wasnt even hot or sweating ... and then my sister was only out for 20 minutes and she was just wearing a short sleeve shirt and she was sweating! .. werid i must of had the cold .... but then I took a 2 hour (day) nap and when I woke up i was burning hot and it was at night, when it wasnt as "Hot" so then I think i had the fever...? ... buyt know its today and i have a headache (little ) i think its becoz of my stomache... becoz know i feel like puking .. but theres not really anything in my stomache 2 throw up .. so i need 2 eat somethin g .. but idk what 2 eat .. (I was gonna have chocalte milk that provides "Breakfast" but we dont have any left ,, thats what worked 4 me last time) .. so any foods thats safe for me to eat .. and make me throw-up and hopefully get rid of this whole SICKNESS .. :( (sorry i spelled stomache wrong idk how 2 spell it .. but its same as belly-ache ) .. anyway best answer will get as many points as i can give , 10.. anyway hope you answer.
