I was planning to lay off the Chinese food last night and see whether it helped my Sunday-night insomnia. However, after the extreme hangover of doom I decided that my sleep patterns were likely to be completely disrupted anyway and I'd probably manage to have insomnia no matter what happened, so I ate Chinese anyway and will do the experiment some other weekend when it has a better chance of being controlled.
Good job too, as it turned out, since I was completely wrong in the other direction and slept like a log. If I'd avoided Chinese just before that happened, then I might have wrongly convinced myself that it was to blame, and sworn off it unnecessarily! That's pretty scary. I hadn't fully considered the risks of this business until now.
In other news, songster pointed out a blog entry suggesting that at least one other person had the same problem as I did with the Star Wars trilogy, so it doesn't seem to be a one-off. How depressing. My second copy has apparently already been dispatched, as well; I bet they just shoved another one in an envelope and didn't actually check it was OK…
