I guess it had to happen at some point: I've gotten myself sick.
I suspect it was all the delicious wok-fried broccoli I ate for dinner last night at the vegetarian restaurant attached to this hotel.
Most of it seems to have been purged from my system, but it took five hours to do so. By 9.30am I was wrung out, exhausted and seriously dehydrated.
One of the girls who shared the same meal as me is fine, so either she's got a stronger constitution or it was something else entirely -- the afternoon latte? -- that got me.
Sadly, it meant missing the morning cooking lesson I was booked on, which I had greatly been looking forward to. But it did mean I could catch up on some sleep while the others went and had a bit of culinary fun. (Mind you, they've all come back in a rather agitated state about seeing dogs being slaughtered at the local market, so it might just be as well I didn't go.)
The rest of the day is free to do what we like, so I'll probably get some more shut-eye before checking out of the hotel at 6pm for our evening plane ride to Chengdu. I suspect I am over the worst of it, and tomorrow I will be back to my normal self. Timing-wise, I'm lucky that this happened on one of our totally free days, it would have been terrible if it happened when we were on the move...
