Don't bring all of your old clothes just to have something to wear. You can always go shopping here. Even name brands are quite reasonable. If you must take regular medication, check if it's available here before stocking up. I also take Anaprox and it is ten times cheaper here.
Western medicine is very cheap here.
It's also sold like candy. You don't need a prescription for anything. Just tell the pharmacy what you want, and they give it to you. A couple bottles of Tums might provide just the thing to reward your stomach with after sampling an exotic or hot dish. Also, if you prefer Kaopectate or Pepto-Bismol, you should bring some with you.
