So I was good (and tired) and toddled off to sleep around midnight, with the full intention of sleeping until 8 a.m. I set an alarm and everything. Then I woke up. I lay in bed half-asleep for about half an hour, with spanish phrases running through my head. I finally decided to get up to review 'haber + infinitive' which was tripping me up yesterday, and found that it was 5:30. So I'm about three hours short on sleep in theory, but wide awake, and I actually do feel fine. Given that the test is at 11 and not, say, 4, I think it'll be okay.
Hungry. Time for tea and a nice solid breakfast, I think. I declare this an officially no-dieting day. :-)
