Sick=Sucks

So apperently I am sick. Monday, I definatly felt sick, though I felt a lot better after my system was purged from vomitting. So I thought on Tuesday I was fine. I ate breakfast and Lunch without problems. Though for some reason I was not hungry until later at night when I ate an egg roll. At about 3 in the morning I saw the egg roll come back the other way. At first I thought it was just a combo of to much pizza and to much stress, now I don't know what is going on. I don't have a temperature. I just have queziness and a problem keeping food down.
