You don't need all that much time. Literally, take 60 seconds to lay there and try to remember, then 30 seconds to write down a couple of one word bullets so you can remember and write it in detail when you get home. If an extra 90 seconds will really screw up your routine, try and wake up two minutes earlier.

But extra sleep does always help. The main reason I was in a slump for most of last month was that I just wasn't sleeping enough.
