It looks like you've made the best move already by recognising that these symptoms even exist in you! Well done
For me, a good day always starts with a good morning. If I have ample time to have breakfast, a quick stretch and a stroll, I find getting in to work stress-less and the rest of the day goes much better than it would otherwise have been.
There are tones of resources on this site about getting up early. The best info I picked up was Steve Pavlina's post about setting the alarm clock early and actually getting out of bed when it goes off! Just remember, the Snooze button is the devil!
hope that helps
