从格尔木开始有高反，头疼、头晕。这滋味不好受，所以基本在铺上躺着。想来是红景天吃的晚了，且和高原安数量吃的不够（才各吃了2粒）。下次来一定提前两周吃，并且一次各吃4粒。下午4时准点抵达拉萨，本想在站前留影，特警不让，只好用手机远远拍了张，留作记念。
Altitude sickness started when the train left from Golmud station, a headache, dizziness, giving me a hard time, so I pretty much just laid down on my bunk. I guess I took the medicine called Hongjingtian too late, and I didn’t have enough of the Gaoyuan’an medicine (I only ate two pills of each type). Next time I’ll definitely take the medicine for two weeks in advance, and take four each time. Arrived in Lhasa right on time at 4 PM, I wanted to take pictures of the station but the Special Police wouldn’t let me. I had to take a picture from far away, set aside for my memory.
