I went Thailand (Chiang Mai) about 1 mth ago and now on Taiwan (24 wks). Quite alright with food and walking around, free and easy trip. I guess just eat everything in moderation? Trial and error. Avoid foods that you'd avoid usually anyway, like raw and semi cooked food.
Actually I rode on an elephant ride in Chiang Mai. It was rather bumpy, but still alright.
