I have Maxolon and Motilium. They're both really good at making you feel more relaxed seeing as you can't actually v* after youve had them. I rarely ever use mine tho.
I got mine on prescription before my doctor knew i was emetophobic and i have kept them now. My doc said, however, that she doesnt mind me having them, as long as thats the only 'saftey thing' i have.
I believe, though, that you can get Motilium over the counter in most countries. When its sold over the counter its called "Motilium 10", but its exactly the same drug.
