Sorry if the title is not politically correct- no offence is attended only I couldnt think of another term for it. My bf has just been told he will have to do his first business trip to India later this summer however he has never been there and is worried about getting "ill" and he has been teased by his mates about getting this condition. I can't seem to find any definitive advice anywhere that matches except for only drinking water from a bottle, any other tips?

Thanks,
