I have become sick with a cold, symptoms include sore throat, ear aches , body pain dry cough. But something weird has been happening. Last night I ate a bowl of cereal before bed and fell asleep. I woke up and puked, a lot but there was no feeling of nauses involved. Then today I ate lunch and had a nap and woke up once again and puked everything up, but did not feel sick to my stomach. What could it be?
