Hey, suck it up and just go. Long ago, I did tours far heavier because 20-25 yrs ago going through S and SE Asia was out and out politically and militarily dangerous. It would be like going through Afghanistan and Iran now.
If you're young and tough mentally and physically, you can't be stopped, not even by those military checkpoints. You just have to keep you head about you and when necessary, speak dollars, not Russian. It's all they understand. And don't count on your embassy to help you out. Embassies won't get you out of a parking ticket.
