Hi, yesterday about 1:00 pm I felt weak. I went upstairs & felt unstable. I went to the bathroom & had diarrhea. I went to my bedroom & felt like I had to go back to the bathroom. #2 diarrhea. I felt dizzy, so I sat on my bed. As I laid down, the ceiling started spinning around. Then I started to vomit, eventually 7 times. I was weak, so I fell asleep. 2 hours later I woke up & drank some water & ate a tuna sandwich. I was okay. What was that? I am a 67 year old make. This year I was able to swim one mile 17 times.
