I have like 7 months left.
Yes, many changes have been made, although I'm not sure the actual itinerary right now.
I now have somewhat of a complex into traveling abroad with celiac disease, which, as I have mentioned before, is an intestinal disorder which basically means i can't eat wheat gluten. This wasn't a problem in australia or the states, but has proven to be quite a significant annoyance in a country where I don't speak the language and the labels are only in another language.
For the general populace, food I can't eat includes:
wheat (most) pasta
pizza
cookies
crackers
most snack/junk food
pizza
burgers
any other form of bread
beer
breaded, fried food
non-breaded food fried in the same vat as breaded fried food
soy sauce
many other sauces/foods (mayonaisse, many commercial dressings) that use wheat or barley as a thickener and don't list it/the food preparers don't know it has gluten in it (restaurants abroad are especially guilty of this)
Unfortunately, with the way things are commercially cooked in Korea, I hardly ever eat out here. They cook pretty much everything in this shit:
which has gluten in it, so basically I can't eat anything unless its plain, which thanks to much of Korean people, as intelligent as they are but lacking any form of common sense/deviation from the norm or the ability to understand it (you should see me order a whiskey/water at the bar" WHAT U MEAN WATER?! WHY?!), almost never happens, so I cook pretty much everything I eat myself. It makes traveling more difficult than I thought it would be.
It may not sound like a big deal, but this isn't exactly something minor like lactose intolerance; when i ingest gluten, it destroys the villi in my small intestine which helps to digest food. After eating no gluten these begin to grow back, but it makes me very tired, weak, and generally somewhat malnourished in the meanwhile, not to mention much harsher future consequences (read: intestinal cancer)
So like I said, not sure. Its definitely possible to do, it just makes shit a lot harder. I should be getting my vacation in another couple months, I'd like to go to Beijing and see the great wall of China, maybe down to Shanghai too. I also plan on visiting thailand/laos/cambodia when i'm finished, but right now its up in the air.
As much of a poor, reckless wanderer i'd like to be wandering on foot from city to city, country to country, with such a dietary restriction it significantly lowers my chances of doing that.
