Argh...I want my hour back

I understand the concept of Daylight Savings, although I'm not sure why we do it at the beginning of April these days rather than the end, like when I was a kid. But considering I went to sleep at ten last night and woke up at ten (new time, making a total of 11 hours' sleep) and I still feel tired...oh, I want that hour back. Still, I have things to do, so must chop-chop. But I always feel a little hung over when we start this. It doesn't help that it's cloudy and much colder this morning, either.
