While on vacation I was eating a healthy meal and started feeling dizzy. Within an hour my entire world was spinning and I started vomiting. The vomit was not typical as it was almost as dry as saw dust. The vomiting lasted about an hour and was followed by short term chills. The spinning started to subside and the nausea went away. The entire incident lasted about 2-3 hours. I slept for several hours following it. Twenty four hours earlier I was on a large airline flight. Up until the incident I was my healthy self. Since that time I feel a little indigestion periodically.
