Care needed at the ‘Coffee Culture’ shops, where even the black coffee with ice has some sort of sweetener (sugar or syrup) added.
That cold sweat from stomach cramps. Glucophage or as a result of the water in Ho Chi Minh?
Not being sure of what would be available on the train to Hanoi (1700km and 36 hours), we stopped at Annam Gourmet Market for a picnic French-style meals of cheese, pate and nuts.
Trolleys of fast food and drink were constantly moving through the train. The coffee, shaved ice with some sort of coffee syrup, which we skipped. Settling for the occasional beer we could get at the main stops and plenty of water. Food was available a couple of times a day. Plastic trays with rice served with some sort of meat looking thing, a bit of green veg, sauce and Pho. One of the meals also had tofu, and pickled egg. Completely manageable if one avoids the obvious rice and noodles. Eat around them. The hidden sugars (from sauces etc) seem to be nominal and diluted.
