Delhi Belly or Montezuma's Revenge what would you do?

I keep pinching myself that I am off to India with an old git on Monday. 

Soon Tony Cartwright and I will be boarding the AVE high speed train in Cordoba bound for Madrid but a thought occurred to me as I read (again) The Rough Guide to India... 

At best 50% of visitors to India suffer from travellers' diarrhoea (TD) so in order to avoid Delhi Belly or Montezuma's Revenge I am going to avoid salads, ice cubes, unpopular street vendors, oh and McDonalds.
