Cases of traveler's diarrhea: NONE! One or two rough mornings after overdoses of a) Chinese "bai jiu" vodka or b) dried peppers and pepper oil, but no cases of illness related to old, spoiled, or dirty food. And that's after 3 months of eating fruits and veggies from vendors, sweet potatoes and pancakes from the same, and meals from dingy little roadside restaurants. Nothing sanitized, nothing wrapped up in plastic, nothing kept in bottles or refrigerators.
Water bottles used in the last two months of the trip: 1! Once I found out that I could get restaurants to refill mine, it was smooth sailing.
If there's anything you'd like to know, ask via comment and I'll do my best to answer. Otherwise, I will fight the temptation to go on listing bizarre and pointless statistics and will get to the point: traveling this way is CHEAP. Anyone can go fauxbo, I guarantee. A month of total freedom costs less than a car payment or a night in a fancy hotel. A month of delicious, fresh, exotic food costs less than a bottle of high-end booze. A week of scenery and frolicking on beaches and in forests costs less than a video game. Sell your car, sell your junk, cancel your lease, come hit the road! You know where to find me.
