My 12 year old has always had a tendency to vomit after a general anaesthetic and used to get quite bad reflux up until he was about 9 but now he has vomited on the last 3 car journeys we have had. Nothing in between car journeys so assuming not a bug/food poisoning. Can anyone recommend some good medication or other ideas. He doesn't read in the car and we switched the dc seats around so he was sat by the window and closer to the front but that didn't make any difference.
