As someone who was in your

As someone who was in your shoes just a few years ago (Physics/Engineering graduate with motivation troubles), I would say the most important things you can do, which I recognize now that I've changed, are:

-Set a routine
-Start a VERY healthy diet. Health has a remarkable affect on energy and motivation. Moderate Coffee or Tea in the AM is valuable as well.
-Become a morning person. One of my greatest influences used to say "Every hour of sleep before 10 PM at night is worth two hours the next morning" and I found this to be quite true.
-Workout in the AM, if even for only 15 minutes. It wakes up the mind and body and allows for focus.

and, as Benjamin Franklin suggests, each morning set your goals, each evening reflect on the goodness of your day.
