While it is lovely feeling to wake up, glance at the clock, and realise you have a couple of hours left, it isn't worth purposefully disrupting your sleep for. Plus, that warm, fuzzy feeling doesn't last very long if you then repeatedly wake up until the alarm goes off.

That happens to me a lot more than I'd like. I get weeks or months where I'll wake up several times a night, sometimes at least once an hour, but it is much worse if I wake up a few hours before an alarm.

The best thing anyone can do is a get as good a sleep as possible.
