As everyone else said, you need more sleep. You might look at your diet, but sleep cannot be supplemented. I wake up at 4:15 every morning, so trust me I know. It's sometimes hard to be in bed by 9-10, but it's necessary. And you can't get extra sleep one night and think it will make up for the last 3. You need to find you sleep needs (I make do with 6 or 6.5), and stick with it.

Also, as someone else pointed out, take a look at how much time it takes you to get ready in the morning. Do you really need 1.5 hours? I would love to read the morning paper with a cup of joe as much as the next guy, but it's just not a luxury that I get. Consider doing some things the night before. I always make my lunch and lay out my clothes the night before and make sure all my bike gear is in "grab and go" condition. Besides adding speed to your morning, evening prep also allows for a mental focus in the morning. Instead of think about "did I get this, I forgot that", you can focus on the day at hand and enjoy the ride.
