It had to happen eventually on this trip -- traveler's diarrhora. It started on the bus trip to Halong Bay, and got going good after boarding the boat for a two-day boat ride, most of which I experienced in my stateroom instead on deck or swimming or kayaking like everyone else. Imodium didn't work on this one, but it was over somewhat in a day. It has also made me very tired (due perhaps to dehydration) which is another reason I have not been online as much as I would like to type in new entries.
