This reminds me of a question I had in a 2nd round interview last year - "What gets you going in the morning" - I responded with an immediate "the alarm clock" - needless to say I didn't get the job!

Normally, I wake up to the alarm clock, if my hubbie is around he has it set early as he leaves/finishes earlier than me and I choose to get up with him as it's the best part of the day for us to get some quality time together. We make and have breakfast together, chat etc before he leaves. If he's away on businesss I admit to having an extra hour in bed and then often have to rush before I need to go out.
A cup of nice coffee also helps.
