DS (11) seems to have developed this. It's a classic picture and is undergoing tests, but it looks most likely. He has vomited and retched about 50 times today and can't keep a teaspoon of water down. The pattern seems to be 12 hours like this then symptoms stop. He's had cyclazine, ondansoteon and diazepam to reduce the symptoms without any affect.
Does anyone have any advice on this awful condition?
