I felt fine until we went out Saturday night. We went to a steakhouse here that we like. We've been there before. I had a couple screwdrivers (never a big deal), and some stuffed mushrooms. About 45 minutes later, I started getting this horrible headache. I just thought I was still hungry, so we ordered dinner. I had a coke with dinner, but my headache just kept worsening. We left to go home, and when I stood up I felt very nauseas. (usually don't really ever get nauseas) About 3/4 of the way home, I had to have my husband pull over. Violently ill. I went to bed immediately when we got home, and slept 11 hours. Yesterday, I felt very weak and dizzy all day, still had a headache. I even took a 3 hour nap in the afternoon, (very unusual for me). I woke up with bloody "D". All last night I woke up about every hour with more "D" (no more blood). This morning, I vomited the water that I had drank during the night. I feel very weak and headachey. Not sure what this is, kinda sounds like food poisoning. What do you guys think?
