Some days, when I'm really tired (if I go to sleep late), I'll wake at 5:00 or 5:30, but that's still earlier than I used to wake up.

如果偶尔有几天我特别累的时候(比如熬夜了)，我会在5：00或者5：30起床，但这仍比我以前起的要早。

The first time I used it it still took me to get to sleep (probably due to revising so late) but I slept throughout the night and when I woke in the morning I felt fully refreshed.

当我第一次用它时，入睡仍然经过了一段时间(可能是因为复习太晚)，但我安安稳稳地睡了一整夜，当我早晨醒来时，感觉完全的精神焕发。
