After sleeplessness during naps 1 and 2, 1730 and 2330 yesterday, ’twas a welcome surprise when I dropped off pretty much immediately at 0530 this morning. I slept the full twenty minutes, perhaps even a minute or two over.

For what it’s worth I’m awake and somewhat coherent. Not really too sleep deprived (yet). Cognition’s acceptable, if a little below ‘well-rested’ – short-term memory’s not great, but I’m functioning at a normalish level overall. I imagine my exam performance this afternoon will be a better indicator of ability during this adjustment phase.
