I'll second that blatz (mmm, beer). I used to wake up and it'd take me a while to get going and actually feel alive. For the last few weeks I've been in the gym by 6 a.m. doing cardio and moderate to heavy lifting. It seems like I have twice as much energy on these days as I do when I don't work out. Today I actually went for a short afternoon jog as well just because I wanted to burn some energy (and the foot long sub I had). Funny enough, working out also seems to suppress my appetite some what. I probably eat as much or more as usual, but I don't crave food. It's a pain to just go and do it those first few days, but once you get in a routine and start feeling the benefits it will become much easier to go.
