I was in perfect shape for two months. I could eat whatever I wanted. Yesterday I went to a restaurant that is safe for me. At least it was the last time I went there. At the end of the meal I began to have a big headache on one side of my head but no GI symptoms. I got home feeling a bit queasy and anxious.I needed to go to the loo. Still no GI symptoms. But the I got a bad case of D, nausea, sweat and dizziness. It went on for a couple of hours until I went to bed exhausted and still nauseous. This morning, the smell or just thinking about food makes me nauseous. My headache is still there and I'm deshydrated. I just can't get out of bed but I can't sleep either. Can't go to work like that. The last time I felt that bad was two years ago when a got sick with ibs for the first time ever. Is it a big ass flare up or just bad luck??
