well maybe to keep him from vomiting take his or her bowl and wash it twice...NOT WITH BLEACH!!! put some ice make sure you used it from tap water or what would be a better idea would be to buy bottles of water from wal mart or any store...make sure your water at home doesnt hav any chemicals or such...he could be touching a spit gland while he drinks...or he might have twisted his stomatch by drinking or eating too fast but try my advice...
sincerly,
