From personal experience, people who are on time are perpetually agrevated when a person is late - I take more time to complete my work, which leaves my collegues waiting for 15 minutes sometimes. I set the alarm on my phone, which helped in meeting up for lunch when in differant areas of the building, and also setting it on vibrate/alarm and keeping it near my pillow worked to.

Do an analysis of what time it takes to prepare in the morning, your commute, and what sorts of delays you may incounter to develop a time line of what you ahve to have done by when. Having a clock in the bathtoom helps, as hot showers can tend to make you linger if your room is chilly at night.

Explain your situation and let the boss know you are working on it - we just went theough an hour transition, but traveling for work, I have a 3 hr adjustment, both at the job site and back in Boston which really skewed my sleep patterns.

One thing to try is to go to bed much earlier then usual and geting in about an hour or so earlier than usual - most people in my office that start at 7 am leave by 3:30 4 pm, which leaves them a few hours of daylight to enjoy, whereas my late morning schedule has me going home at 6:30-7 pm.

Find out what works best and procede accordingly, as the warmer weather should leave you less prone to hybernation.
