Thank you all - especially mizzsocial. I spoke to Mum on the phone today and she said it might be the MSG in it. It's funny because 2 weeks ago we went to our normal Chinese and both of us were fine and loved it. This was a different Chinese place we went to so I guess it possible that we were both affected by a higher level of MSG. Hopefully it will settle in the next few days. Yoghurt is helping for now and I'm going to get some Yakult tonight so I'm hopeing that will help too.
